Hi-Draw Check Valve Injector Kit for Downstream

Upgrade your pressure washing setup with our premium stainless steel downstream injector kit. Crafted from 100% stainless steel, this kit minimizes the risk of corrosion while maximizing soap draw for superior cleaning results. Unlike traditional injectors, our innovative design replaces the spring and ball with a reliable check valve, eliminating the common failure point. This kit is specifically designed to attach to a GP Hi-Draw Injector, ensuring compatibility and seamless integration. For optimal performance, we recommend using Teflon tape or a high-quality liquid sealant during installation. Enhance your pressure washing capabilities with our durable and efficient downstream injector kit for a higher soap draw and exceptional cleaning power.
