QC ADJ CHEM INJECTOR ASSY 5-8GPM 2.3mm

SKU: 4605

QC ADJ CHEM INJECTOR ASSY 5-8GPM 2.3mm — an adjustable downstream chemical injector sized for 5-8 GPM pressure washers. The 2.3mm orifice is matched to high-flow commercial pumps: it creates the venturi draw that pulls detergent into the water stream at low pressure without restricting the pump, so soap-and-rinse cycles work without running chemical through the pump. If your machine flows 5 GPM or more, this is the correct size — a smaller injector would choke a high-flow pump. How to choose: match the injector orifice to your pump's flow — 1.8mm for 2-3 GPM machines (SKU 4603), 2.1mm for 3-5 GPM machines (SKU 4604), 2.3mm for 5-8 GPM machines (SKU 4605). An injector sized for a bigger machine won't draw chemical properly on a small pump, and an undersized one restricts a high-flow pump. Sold by CheapPartz as SKU 4605.
