3/8″ Injector Bypass Kit – Supports 3–7 GPM Flow

The 3/8″ 3–7 GPM Injector with Bypass Kit is a complete downstream chemical injection and bypass solution designed for softwash and pressure washing systems. Built to handle flow rates between 3 to 7 gallons per minute (GPM), this kit allows for efficient chemical application and quick switching between soap and rinse modes. The integrated bypass valve lets users shut off chemical draw without removing the injector, improving efficiency and extending injector life. It’s ideal for use with SH (sodium hypochlorite), surfactants, and other softwash solutions. This kit is sold unassembled.
