Simpson Dial-N-Wash Adjustable Pressure Regulator, 4500 PSI, M22 Quick Connect, Twist Control for Precise Cleaning, Gas or Electric Pressure Washer and Power Washer Accessory, Cold-Water Only (82232)

The Simpson Cleaning 82232 Dial-N-Wash Adjustable Pressure Regulator for Pressure Washers, rated up to 4500 PSI, is a great product. I used it for the first time yesterday and attached it to the bottom of the gun. It's working well, providing precise pressure control for different cleaning tasks. The build quality feels solid, and it enhances the versatility of my pressure washer. Highly recommended for anyone needing adjustable pressure settings.

Works great. Easy to use. You can dial any pressure on the fly. If say, you are washing your car you can have a nice easy pressure on the paint then without missinf a beat blast the wheels and wheel wells. If you have a non adjustable pressure washer than this is a cheap and easy solution

We do a lot of pressure washing in the spring. We have three different pressure washers and adjustment works very well. On one of the pressure washers it tends to want to move on me so I have to pay attention if I want it to stay on max. We bought it because we wanted to clean our asphalt driveway and you can only have 800 PSI on asphalt so we can dial it down. This easy to install.

Used this onesie the pressure on my 3200psi pressure washer while using a surface cleaner. The water from the surface cleaner jets were a bit strong and sometimes left lines on my concrete driveway. I used this to dial back the pressure just a bit and it worked perfectly. Highly recommend so you can adjust to the surface you are cleaning.

This adjustable device allows you to easily manage the amount of water pressure as you use the device. You can lower pressure for more fragile materials and raise pressure for tougher materials. Since this device attaches to the wand it adjusts literally at your fingertips. For the price this item is excellent.

Same brand as my power washer. Easy to install but didn't quite provide a range of pressure I expected. Low settings was still nearly full. Be careful using in somewhat "fragile" items expecting low pressure. I damaged some screens even though set on the lowest setting.

I was surprised that this Simpson dial pressure adjustment really worked. I placed it on the bottom of a stubby washer gun, between the hose and bottom of gun. The pictures show it going between the gun handle and barrel, but I did not want to rip apart my well worn spray gun to do that. Instead, I used it on my separate Tool Daily branded spray gun and it is awesome! I personally don't use it on vehicles, but that all depends on the strength of your machine.

Purchased in March 2025. Work fine. Used for washing cars. September 2025. It stopped reducing pressure, only runs at full pressure. Simpson requires taking it to an authorized service center. For me, the gasoline cost to drive there and back exceeds the cost to buy one.

Works well very happy

This is a must have for anyone who wants to reduce the pressure on the wand… Solid, well made and easy to use.

Funciona excelente

If you have a pressure washer and it doesn't have one of these then you are missing out.
