    • Great piece of equipment for pressure washers.
Style: Ball Valve
Makes pressure washing easier than ever with just a valve to turn water on and off just like that. Hasn’t failed on me yet and don’t think it will.

    • Works great!
Style: Short Gun
I don’t use a high-end pressure washer because I’m cheap, but I recently decided to make some quality of life upgrades to my setup for car detailing. I love this pressure washer gun! It is such an upgrade over the stock lance provided by my washer’s manufacturer (Greenworks). The first thing I noticed was I had higher water flow when using the provided tips. They are a higher GPM volume than what I was working with before which makes my life a little easier, especially when washing larger vehicles like trucks and SUV’s. Tha handle is plastic, and the interior is all steel & brass. The fittings are tight and don’t leak. I especially like the swivel because I’m a mess and can’t keep my hoses straight. I’ve detailed several cars since I purchased it two months ago and it still works as intended. The handle is a bit stiff and can cause fatigue if you have to hold it in the active position for a long time, but other than that minor gripe, I’m super satisfied!! ... show more

    • Leaks from the handle
Style: Ball Valve
Poor quality. Leaks from the handle well under its alleged pressure rating.

    • A great accessory for your pressure washer
Style: Short Gun
Shipped quickly and packaged well. The compact design is exactly what I was looking for to use with my foam cannon while washing my car as well as by itself for rinsing it. A great product and very good value.

    • Basically a high pressure complete shutoff ball valve...
Style: Ball Valve
Got this so I can cut off my pressure washer's pressure when I switch from my foam cannon to my washing wand and it works perfectly. Much easier (and less messy) to completely cut off the high pressure water flow and not have to fiddle with pressurized connections and get wet. Just remember to not leave it closed for a long time as your pressure washer pump will overheat and fail. Normal ball valves don't have the pressure ratings to withstand the high pressure your pressure washer pump will develop so a full port high pressure ball valve is required. This one came with the necessary male and female fittings so fitting it up was a simple matter of applying Teflon sealing tape and tightening the fittings up and installing the valve on the high pressure port. The seller even includes a roll of Teflon pipe tape for that purpose. ... show more
