Check all connections for leaks before starting work.\u003c\/p\u003e\n\u003cp\u003eInspect accessories before each use. Check for cracks, wear, loose connections, and damaged seals. A wand or gun that breaks under pressure is a safety hazard.\u003c\/p\u003e\n\u003cp\u003eClean accessories after each use. Chemical residue corrodes metal parts and degrades seals. Flush with clean water before storing.\u003c\/p\u003e\n\u003cp\u003eStore accessories indoors or under cover. UV exposure degrades rubber and plastic components. Cold weather can crack fittings with trapped water. Drain everything before storage in freezing conditions.\u003c\/p\u003e\n\u003cp\u003eBuild a maintenance routine for your accessories. At the start of each work day, check trigger gun seals, wand connections, and hose fittings. Look for worn O-rings, cracked barbs, and loose quick connects. At the end of each day, flush chemical residue from everything and hang hoses on the reel. These habits add years of life to your equipment and prevent surprises on the job.\u003c\/p\u003e\n\u003cp\u003eWhen an accessory breaks on a job, having a backup on the truck is the difference between finishing the job and going home. Keep a spare trigger gun, a spare set of nozzles, extra quick connects, and a length of jumper hose on your rig at all times. The cost of a few spare parts is nothing compared to the cost of a lost job.\u003c\/p\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat PSI rating do I need for my hose?\u003c\/h3\u003e\n\u003cp\u003eMatch the PSI rating of the accessory to your pressure washer's output. Using an accessory rated below your system pressure is a safety hazard. It is fine to use an accessory rated higher than your system pressure. Higher-rated parts work at lower pressures without any issues.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between a consumer and professional accessory?\u003c\/h3\u003e\n\u003cp\u003eProfessional accessories use heavier construction, higher pressure ratings, chemical-resistant materials, and serviceable connections. Consumer accessories use lighter materials and are often not rebuildable.

Wrap clockwise when looking at the end of the fitting. Hand tighten first, then snug with a wrench. Do not over-tighten brass. Brass is softer than steel and will crack if you force it.\u003c\/p\u003e\n\u003cp\u003eFor connections above 3000 PSI, use pipe dope (thread sealant) instead of or in addition to Teflon tape. Pipe dope fills thread gaps better under high pressure.\u003c\/p\u003e\n\u003cp\u003eAfter install, pressurize the system and check every connection for leaks. Fix leaks right away. A slow drip becomes a blown fitting under full pressure. Inspect your fittings regularly for corrosion, hairline cracks, and thread damage.

The threads are tapered and seal with Teflon tape or pipe dope. BSP (British Standard Pipe) comes in parallel and tapered versions. NPT and BSP are not interchangeable even when the sizes look similar. If your equipment was made overseas, check for BSP threads before ordering.\u003c\/p\u003e\n\u003ch3\u003eCan I use brass fittings with bleach and sodium hypochlorite?\u003c\/h3\u003e\n\u003cp\u003eYes. Brass handles sodium hypochlorite (SH) well at the concentrations used in pressure washing, typically 10 to 12.5 percent. For long-term chemical exposure, stainless steel lasts longer, but brass is the standard and works fine for most setups.\u003c\/p\u003e\n\u003ch3\u003eWhat size fitting do I need for my pressure washer?\u003c\/h3\u003e\n\u003cp\u003eMost residential pressure washers use 1\/4 inch fittings. Commercial units typically use 3\/8 inch. Larger systems and hot water units often use 1\/2 inch or 3\/4 inch. Check the ports on your pump and equipment to match the correct size.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy pressure washer fittings and adapters near Gaithersburg, Maryland?\u003c\/h3\u003e\n\u003cp\u003eSun Brite Supply is located at 16620 Oakmont Ave, Gaithersburg, MD 20877.

Wrap clockwise when looking at the end of the fitting. Hand tighten first, then snug with a wrench. Do not over-tighten brass. Brass is softer than steel and will crack if you force it.\u003c\/p\u003e\n\u003cp\u003eFor connections above 3000 PSI, use pipe dope (thread sealant) instead of or in addition to Teflon tape. Pipe dope fills thread gaps better under high pressure.\u003c\/p\u003e\n\u003cp\u003eAfter install, pressurize the system and check every connection for leaks. Fix leaks right away. A slow drip becomes a blown fitting under full pressure. Inspect your fittings regularly for corrosion, hairline cracks, and thread damage. Replace any fitting that shows wear.\u003c\/p\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is the difference between NPT and BSP threads?\u003c\/h3\u003e\n\u003cp\u003eNPT (National Pipe Thread) is the US standard. The threads are tapered and seal with Teflon tape or pipe dope. BSP (British Standard Pipe) comes in parallel and tapered versions. NPT and BSP are not interchangeable even when the sizes look similar. If your equipment was made overseas, check for BSP threads before ordering.\u003c\/p\u003e\n\u003ch3\u003eCan I use brass fittings with bleach and sodium hypochlorite?\u003c\/h3\u003e\n\u003cp\u003eYes. Brass handles sodium hypochlorite (SH) well at the concentrations used in pressure washing, typically 10 to 12.5 percent. For long-term chemical exposure, stainless steel lasts longer, but brass is the standard and works fine for most setups.\u003c\/p\u003e\n\u003ch3\u003eWhat size fitting do I need for my pressure washer?\u003c\/h3\u003e\n\u003cp\u003eMost residential pressure washers use 1\/4 inch fittings. Commercial units typically use 3\/8 inch. Larger systems and hot water units often use 1\/2 inch or 3\/4 inch. Check the ports on your pump and equipment to match the correct size.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy pressure washer fittings and adapters near Gaithersburg, Maryland?\u003c\/h3\u003e\n\u003cp\u003eSun Brite Supply is located at 16620 Oakmont Ave, Gaithersburg, MD 20877.

Wrap clockwise when looking at the end of the fitting. Hand tighten first, then snug with a wrench. Do not over-tighten brass. Brass is softer than steel and will crack if you force it.\u003c\/p\u003e\n\u003cp\u003eFor connections above 3000 PSI, use pipe dope (thread sealant) instead of or in addition to Teflon tape. Pipe dope fills thread gaps better under high pressure.\u003c\/p\u003e\n\u003cp\u003eAfter install, pressurize the system and check every connection for leaks. Fix leaks right away. A slow drip becomes a blown fitting under full pressure. Inspect your fittings regularly for corrosion, hairline cracks, and thread damage.

The threads are tapered and seal with Teflon tape or pipe dope. BSP (British Standard Pipe) comes in parallel and tapered versions. NPT and BSP are not interchangeable even when the sizes look similar. If your equipment was made overseas, check for BSP threads before ordering.\u003c\/p\u003e\n\u003ch3\u003eCan I use brass fittings with bleach and sodium hypochlorite?\u003c\/h3\u003e\n\u003cp\u003eYes. Brass handles sodium hypochlorite (SH) well at the concentrations used in pressure washing, typically 10 to 12.5 percent. For long-term chemical exposure, stainless steel lasts longer, but brass is the standard and works fine for most setups.\u003c\/p\u003e\n\u003ch3\u003eWhat size fitting do I need for my pressure washer?\u003c\/h3\u003e\n\u003cp\u003eMost residential pressure washers use 1\/4 inch fittings. Commercial units typically use 3\/8 inch. Larger systems and hot water units often use 1\/2 inch or 3\/4 inch.

Wrap clockwise when looking at the end of the fitting. Hand tighten first, then snug with a wrench. Do not over-tighten brass. Brass is softer than steel and will crack if you force it.\u003c\/p\u003e\n\u003cp\u003eFor connections above 3000 PSI, use pipe dope (thread sealant) instead of or in addition to Teflon tape. Pipe dope fills thread gaps better under high pressure.\u003c\/p\u003e\n\u003cp\u003eAfter install, pressurize the system and check every connection for leaks. Fix leaks right away. A slow drip becomes a blown fitting under full pressure. Inspect your fittings regularly for corrosion, hairline cracks, and thread damage. Replace any fitting that shows wear.\u003c\/p\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is the difference between NPT and BSP threads?\u003c\/h3\u003e\n\u003cp\u003eNPT (National Pipe Thread) is the US standard. The threads are tapered and seal with Teflon tape or pipe dope. BSP (British Standard Pipe) comes in parallel and tapered versions. NPT and BSP are not interchangeable even when the sizes look similar. If your equipment was made overseas, check for BSP threads before ordering.\u003c\/p\u003e\n\u003ch3\u003eCan I use brass fittings with bleach and sodium hypochlorite?\u003c\/h3\u003e\n\u003cp\u003eYes. Brass handles sodium hypochlorite (SH) well at the concentrations used in pressure washing, typically 10 to 12.5 percent. For long-term chemical exposure, stainless steel lasts longer, but brass is the standard and works fine for most setups.\u003c\/p\u003e\n\u003ch3\u003eWhat size fitting do I need for my pressure washer?\u003c\/h3\u003e\n\u003cp\u003eMost residential pressure washers use 1\/4 inch fittings. Commercial units typically use 3\/8 inch. Larger systems and hot water units often use 1\/2 inch or 3\/4 inch. Check the ports on your pump and equipment to match the correct size.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy pressure washer fittings and adapters near Gaithersburg, Maryland?\u003c\/h3\u003e\n\u003cp\u003eSun Brite Supply is located at 16620 Oakmont Ave, Gaithersburg, MD 20877.

Wrap clockwise when looking at the end of the fitting. Hand tighten first, then snug with a wrench. Do not over-tighten brass. Brass is softer than steel and will crack if you force it.\u003c\/p\u003e\n\u003cp\u003eFor connections above 3000 PSI, use pipe dope (thread sealant) instead of or in addition to Teflon tape. Pipe dope fills thread gaps better under high pressure.\u003c\/p\u003e\n\u003cp\u003eAfter install, pressurize the system and check every connection for leaks. Fix leaks right away. A slow drip becomes a blown fitting under full pressure. Inspect your fittings regularly for corrosion, hairline cracks, and thread damage. Replace any fitting that shows wear.\u003c\/p\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is the difference between NPT and BSP threads?\u003c\/h3\u003e\n\u003cp\u003eNPT (National Pipe Thread) is the US standard. The threads are tapered and seal with Teflon tape or pipe dope. BSP (British Standard Pipe) comes in parallel and tapered versions. NPT and BSP are not interchangeable even when the sizes look similar. If your equipment was made overseas, check for BSP threads before ordering.\u003c\/p\u003e\n\u003ch3\u003eCan I use brass fittings with bleach and sodium hypochlorite?\u003c\/h3\u003e\n\u003cp\u003eYes. Brass handles sodium hypochlorite (SH) well at the concentrations used in pressure washing, typically 10 to 12.5 percent. For long-term chemical exposure, stainless steel lasts longer, but brass is the standard and works fine for most setups.\u003c\/p\u003e\n\u003ch3\u003eWhat size fitting do I need for my pressure washer?\u003c\/h3\u003e\n\u003cp\u003eMost residential pressure washers use 1\/4 inch fittings. Commercial units typically use 3\/8 inch. Larger systems and hot water units often use 1\/2 inch or 3\/4 inch. Check the ports on your pump and equipment to match the correct size.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy pressure washer fittings and adapters near Gaithersburg, Maryland?\u003c\/h3\u003e\n\u003cp\u003eSun Brite Supply is located at 16620 Oakmont Ave, Gaithersburg, MD 20877.

Wrap clockwise when looking at the end of the fitting. Hand tighten first, then snug with a wrench. Do not over-tighten brass. Brass is softer than steel and will crack if you force it.\u003c\/p\u003e\n\u003cp\u003eFor connections above 3000 PSI, use pipe dope (thread sealant) instead of or in addition to Teflon tape. Pipe dope fills thread gaps better under high pressure.\u003c\/p\u003e\n\u003cp\u003eAfter install, pressurize the system and check every connection for leaks. Fix leaks right away. A slow drip becomes a blown fitting under full pressure. Inspect your fittings regularly for corrosion, hairline cracks, and thread damage.

The threads are tapered and seal with Teflon tape or pipe dope. BSP (British Standard Pipe) comes in parallel and tapered versions. NPT and BSP are not interchangeable even when the sizes look similar. If your equipment was made overseas, check for BSP threads before ordering.\u003c\/p\u003e\n\u003ch3\u003eCan I use brass fittings with bleach and sodium hypochlorite?\u003c\/h3\u003e\n\u003cp\u003eYes. Brass handles sodium hypochlorite (SH) well at the concentrations used in pressure washing, typically 10 to 12.5 percent. For long-term chemical exposure, stainless steel lasts longer, but brass is the standard and works fine for most setups.\u003c\/p\u003e\n\u003ch3\u003eWhat size fitting do I need for my pressure washer?\u003c\/h3\u003e\n\u003cp\u003eMost residential pressure washers use 1\/4 inch fittings. Commercial units typically use 3\/8 inch. Larger systems and hot water units often use 1\/2 inch or 3\/4 inch. Check the ports on your pump and equipment to match the correct size.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy pressure washer fittings and adapters near Gaithersburg, Maryland?\u003c\/h3\u003e\n\u003cp\u003eSun Brite Supply is located at 16620 Oakmont Ave, Gaithersburg, MD 20877.

If your equipment was made overseas, check for BSP threads before ordering.\u003c\/p\u003e\n\u003ch3\u003eCan I use brass fittings with bleach and sodium hypochlorite?\u003c\/h3\u003e\n\u003cp\u003eYes. Brass handles sodium hypochlorite (SH) well at the concentrations used in pressure washing, typically 10 to 12.5 percent. For long-term chemical exposure, stainless steel lasts longer, but brass is the standard and works fine for most setups.\u003c\/p\u003e\n\u003ch3\u003eWhat size fitting do I need for my pressure washer?\u003c\/h3\u003e\n\u003cp\u003eMost residential pressure washers use 1\/4 inch fittings. Commercial units typically use 3\/8 inch. Larger systems and hot water units often use 1\/2 inch or 3\/4 inch. Check the ports on your pump and equipment to match the correct size.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy pressure washer fittings and adapters near Gaithersburg, Maryland?\u003c\/h3\u003e\n\u003cp\u003eSun Brite Supply is located at 16620 Oakmont Ave, Gaithersburg, MD 20877.

Wrap clockwise when looking at the end of the fitting. Hand tighten first, then snug with a wrench. Do not over-tighten brass. Brass is softer than steel and will crack if you force it.\u003c\/p\u003e\n\u003cp\u003eFor connections above 3000 PSI, use pipe dope (thread sealant) instead of or in addition to Teflon tape. Pipe dope fills thread gaps better under high pressure.\u003c\/p\u003e\n\u003cp\u003eAfter install, pressurize the system and check every connection for leaks. Fix leaks right away. A slow drip becomes a blown fitting under full pressure. Inspect your fittings regularly for corrosion, hairline cracks, and thread damage. Replace any fitting that shows wear.\u003c\/p\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is the difference between NPT and BSP threads?\u003c\/h3\u003e\n\u003cp\u003eNPT (National Pipe Thread) is the US standard. The threads are tapered and seal with Teflon tape or pipe dope. BSP (British Standard Pipe) comes in parallel and tapered versions. NPT and BSP are not interchangeable even when the sizes look similar. If your equipment was made overseas, check for BSP threads before ordering.\u003c\/p\u003e\n\u003ch3\u003eCan I use brass fittings with bleach and sodium hypochlorite?\u003c\/h3\u003e\n\u003cp\u003eYes. Brass handles sodium hypochlorite (SH) well at the concentrations used in pressure washing, typically 10 to 12.5 percent. For long-term chemical exposure, stainless steel lasts longer, but brass is the standard and works fine for most setups.\u003c\/p\u003e\n\u003ch3\u003eWhat size fitting do I need for my pressure washer?\u003c\/h3\u003e\n\u003cp\u003eMost residential pressure washers use 1\/4 inch fittings. Commercial units typically use 3\/8 inch. Larger systems and hot water units often use 1\/2 inch or 3\/4 inch. Check the ports on your pump and equipment to match the correct size.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy pressure washer fittings and adapters near Gaithersburg, Maryland?\u003c\/h3\u003e\n\u003cp\u003eSun Brite Supply is located at 16620 Oakmont Ave, Gaithersburg, MD 20877.

A $5 spare in your truck costs you nothing.\u003c\/p\u003e \u003ch2\u003eInstallation and Maintenance Tips\u003c\/h2\u003e\n\u003cp\u003eWrap male NPT threads with 3 to 5 wraps of Teflon tape. Wrap clockwise when looking at the end of the fitting. Hand tighten first, then snug with a wrench. Do not over-tighten brass. Brass is softer than steel and will crack if you force it.\u003c\/p\u003e\n\u003cp\u003eFor connections above 3000 PSI, use pipe dope (thread sealant) instead of or in addition to Teflon tape. Pipe dope fills thread gaps better under high pressure.\u003c\/p\u003e\n\u003cp\u003eAfter install, pressurize the system and check every connection for leaks. Fix leaks right away. A slow drip becomes a blown fitting under full pressure. Inspect your fittings regularly for corrosion, hairline cracks, and thread damage. Replace any fitting that shows wear.\u003c\/p\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is the difference between NPT and BSP threads?\u003c\/h3\u003e\n\u003cp\u003eNPT (National Pipe Thread) is the US standard. The threads are tapered and seal with Teflon tape or pipe dope. BSP (British Standard Pipe) comes in parallel and tapered versions. NPT and BSP are not interchangeable even when the sizes look similar. If your equipment was made overseas, check for BSP threads before ordering.\u003c\/p\u003e\n\u003ch3\u003eCan I use brass fittings with bleach and sodium hypochlorite?\u003c\/h3\u003e\n\u003cp\u003eYes. Brass handles sodium hypochlorite (SH) well at the concentrations used in pressure washing, typically 10 to 12.5 percent. For long-term chemical exposure, stainless steel lasts longer, but brass is the standard and works fine for most setups.\u003c\/p\u003e\n\u003ch3\u003eWhat size fitting do I need for my pressure washer?\u003c\/h3\u003e\n\u003cp\u003eMost residential pressure washers use 1\/4 inch fittings. Commercial units typically use 3\/8 inch. Larger systems and hot water units often use 1\/2 inch or 3\/4 inch. Check the ports on your pump and equipment to match the correct size.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy pressure washer fittings and adapters near Gaithersburg, Maryland?\u003c\/h3\u003e\n\u003cp\u003eSun Brite Supply is located at 16620 Oakmont Ave, Gaithersburg, MD 20877.
