Product Overview
1/4 inch brass fitting with MPT threads for pressure washer plumbing.
Brass is the standard choice for pressure wash fittings. Handles high temperatures and chemical exposure. Will not rust. Standard choice for pressure wash plumbing. Every connection in your system matters. A single bad fitting causes leaks, pressure drops, and wasted time on the job.
MPT: Male Pipe Thread. Tapered thread that seals with Teflon tape or pipe dope. Make sure your mating connection is the correct thread type before ordering. NPT threads are not compatible with BSP threads, even if the sizes look the same.

Compatibility
Standard NPT fittings connect to any equipment with matching NPT threads. Common connections in a pressure washing rig include:
- Pump inlet and outlet ports
- Unloader valve connections
- Chemical injection points and downstream injectors
- Hose connections and quick connect adapters
- Spray gun inlets
- Buffer tank outlets and float valve assemblies
- Hot water coil connections
If you are connecting two different sizes or thread types, check our adapter fittings section. We carry reducers, bushings, and cross-thread adapters in brass and stainless.
Applications and Use Cases
Pressure wash rigs need reliable plumbing. Every fitting is a potential leak point. The right fitting, properly installed, holds pressure and stays leak-free for years.
- Rig plumbing builds on trailer mounts and skid systems
- Pump connections on inlet and outlet ports
- Chemical injection plumbing for downstream and X-Jet setups
- Hot water systems where fittings need to handle heat and pressure
- Field repair when a corroded or damaged fitting needs replacement on the job
Keep a few common fittings in your parts box. A cracked fitting on a job costs you hours. A $5 spare in your truck costs you nothing.
Installation and Maintenance Tips
Wrap 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.
For 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.
After 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.
Frequently Asked Questions
What is the difference between NPT and BSP threads?
NPT (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.
Can I use brass fittings with bleach and sodium hypochlorite?
Yes. 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.
What size fitting do I need for my pressure washer?
Most 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.

Before You Order: What to Check
Getting the right part the first time saves you a return trip and more downtime. Before you add this to your cart, check these things:
- Model number: Find the model and serial number on your equipment data plate. Write it down before you order.
- Port sizes and thread types: Measure your connections. A 3/8 inch fitting will not thread into a 1/4 inch port no matter how hard you try.
- Pressure and flow ratings: Make sure the replacement part is rated for your system's PSI and GPM. Under-rated parts fail fast.
- Old part comparison: If possible, remove the old part and compare it side by side with the product photos and specs listed here.
- Still not sure? Call us before you order. We would rather spend 5 minutes on the phone confirming fitment than process a return because the wrong part showed up.
