Pressure Washer Adjustable Chemical Injector – Low Pressure

Apply Detergents Safely and Effectively — Keep Harsh Chemicals Out of Your Pump

Take control of your pressure washer’s chemical application with this Adjustable Low Pressure Chemical Injector. Designed for downstream use, this injector ensures that detergents and cleaners bypass your pump entirely—extending the life of your equipment while delivering powerful cleaning results.

Ideal for automotive, siding, fence, and surface cleaning, this injector pulls detergent from a container and blends it into the water stream after the pump. This method prevents premature wear caused by corrosive or soapy solutions circulating through your high-pressure components.

With its adjustable metering valve, you can fine-tune your detergent concentration to match the task at hand—whether you're lightly washing windows or hitting greasy concrete with everything you've got. Quick connect fittings make it easy to install between your pump and high-pressure hose, saving time on setup and cleanup.

Built tough to handle frequent use, this injector is a smart upgrade for anyone who needs versatility and protection when cleaning with chemicals.
