Pressure Washer Guns

A pressure washer spray gun is one of the most important components of your washing system. Designed to be held in one hand, they use a large trigger that the user controls by squeezing when pressure water is needed and releasing when not needed. They are generally made of hard, durable plastic with metal inner components, and have an inlet where water comes in and an outlet where water comes out. Typically, a wand is installed on a pressure wash gun to properly direct the spray, while a hose runs from the pressure washer to deliver pressured water to the gun.

There are several important things to consider when purchasing a pressure washing gun. Arguably the most important detail to look for is the PSI rating of the gun. This tells you if the gun will be able to handle the amount of pressure coming from your pressure washer unit. Make sure the PSI rating of your spray gun is higher than your pressure washer to ensure consistent, safe operation and avoid damage to the gun. For example, if your pressure washer is putting out a maximum of 5200 PSI pressure, a 5000 PSI spray gun would be a great choice. Similarly, you'll want your pressure washer gun to be rated for the same flow rate (or just over) that of your pressure washer. You'll also want to pay attention to the size of the inlet and outlet ports on a gun to make sure they match the connection points on your hose assemblies and wands.

Other Considerations When Choosing a Pressure Washer Spray Gun

Aside from the main points like PSI rating, GPM rating, and port sizes, there may be additional items to think about before you purchase a pressure wash gun for certain applications. If you are power washing with hot water, it's important to check the maximum temperature rating of a spray gun to make sure it can handle the heat level of the water coming from your pressure washer. If the rating is not high enough, you may damage the gun and even be at risk of dangerous leakage with hot water that could cause injury.

Another thing you might not think about is the comfortability factor. If you or an employee will be using the spray gun for extensive periods of time, you should consider finding a gun with an ergonomic comfort grip and an easy-pull trigger. The initial cost will be higher than a standard gun, but reducing fatigue allows jobs to get done faster and more safely. Keep this tip in mind if you frequently encounter situations like having to clean unusually large walls or surfaces with stubborn, baked on dirt and grime that require long bouts of spraying.
