Downstream Fixed 20% 3 – 5 GPM Chemical Draw Injector - Assy

Overview

This is a fixed 20% downstream chemical injector assembly sized for pressure washers flowing 3–5 GPM, rated to a 4500 PSI maximum. It quick-connects after the pump and before your 3/8" high-pressure hose, drawing soap at low pressure when you switch to a short-range black soap tip or a size 40.0 blue long-range tip. Because the chemical enters downstream of the pump, it never runs through the pump — that protects internals and opens up a wider choice of chemicals. The assembly includes 4 feet of chemical hose with a strainer. Note: the injector may arrive plumbed backwards for your setup; if it won't draw, swap the fittings so the flow arrow points downstream, away from the machine.
