Downstream Bypass 6-10 GPM @ 20% Chem Injector 3/8" QCs & Plated Fittings

Overview

This is a fully assembled downstream bypass chemical injector kit sized for 6-10 GPM pressure washers, built around a 20% fixed-draw 2.3mm GP injector body. Unlike a standard downstream injector, the bypass design lets you switch between chemical application and high-pressure rinse with the plated ball valve — no pressure loss, no flow restriction, and longer reach at higher elevations. It draws heavier concentrations of liquid chlorine or other cleaning chemicals downstream of the pump, so chemical never runs through your pump. The kit includes 3/8" plated quick couplers (for 3/8" ID hose), an inlet strainer, a 48" chemical suction hose, and a 24" high-pressure bypass hose. A solid setup for heavy-use or entry-level soft washing on cold or hot water machines.
