Installation and Maintenance Tips
Install accessories with the correct thread sealant (Teflon tape for NPT, rubber washer for GHT). Check all connections for leaks before starting work.
Inspect 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.
Clean accessories after each use. Chemical residue corrodes metal parts and degrades seals. Flush with clean water before storing.
Store 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.
Build 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.
When 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.
Frequently Asked Questions
What PSI rating do I need for my gun?
Match 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.
What is the difference between a consumer and professional accessory?
Professional accessories use heavier construction, higher pressure ratings, chemical-resistant materials, and serviceable connections. Consumer accessories use lighter materials and are often not rebuildable. For daily commercial use, professional-grade equipment is worth the investment.
Do I need any adapters?
It depends on your existing connections. Most professional pressure washers use standard 3/8 inch NPT and 1/4 inch quick connect fittings. Some consumer machines use M22 threads or proprietary connections. Check your equipment and order the appropriate adapter if needed.

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.
