PA 2.1 FIXED INJECTOR QC KIT (plug in/socket out)

SKU: 2601

A downstream chemical injector installs after the pump: water entering the inlet creates a venturi that drops pressure and draws chemical from a container, so soap is added to the water stream without running chemicals through the pump. A built-in check valve prevents backflow into the chemical container in high-pressure mode. This PA fixed (non-adjustable) injector uses a 2.1mm orifice, sized for 3–5 GPM pumps. A fixed injector draws at a set rate with no metering adjustment — simpler and cheaper than an adjustable unit, at the cost of fine control over the soap ratio. This QC kit version carries a quick-connect plug on the inlet and a quick-connect socket on the outlet, so it snaps between the pump outlet and the high-pressure hose with no threading. It draws chemical only at low pressure, so pair it with a soap nozzle or dual lance. Listed as SKU 2601.
