High-Performance Materials: Made from U.S.-sourced stainless steel, brass, and ceramic components, this system handles flow rates of 3.0–5.0 GPM and meets OSHA and ANSI standards. It’s built for durability, safety, and professional-grade reliability.

📓FREQUENTLY ASKED QUESTIONS

A: The Pressure Washer Downstream Chemical Injector Bypass Kit is not compatible with all pressure washers. It's designed specifically for washers with flow rates between 3.0 - 5.0 GPM and requires 3/8" quick connections and NPT outlets. You'll need to check your washer's flow rate and connection type to confirm compatibility.

Q: What chemicals work?

A: The Pressure Washer Downstream Chemical Injector Bypass Kit works with most standard pressure washer chemicals, including detergents, soaps, and cleaning solutions designed for downstream injection. The ceramic ball and Viton seals are compatible with general-purpose pressure washer detergents. For best results, use chemicals formulated for downstream injection systems and check your pressure washer manual to confirm compatibility with your specific products.
