Overview

This is a downstream chemical injector with a fixed 10% dilution ratio, built for pressure washers flowing 2–3 GPM and rated to 4500 PSI maximum. It quick-connects inline after the pump and before your 3/8" high-pressure hose, drawing soap only when you switch to a low-pressure soap nozzle — a size 40.0 black short-range tip or blue long-range tip. Because the chemical enters the line downstream, it never runs through the pump, which protects your seals and lets you run a wider range of chemicals. It ships with 4 feet of draw hose with a strainer. If yours arrives plumbed backwards, just swap the fittings so the flow arrow points downstream, away from the machine.

Frequently asked questions

It fits pressure washers flowing 2–3 GPM at up to 4500 PSI. It installs downstream of the pump — quick-connect it between the pump outlet and your 3/8" high-pressure hose.

Switch to a low-pressure soap nozzle — a size 40.0 black short-range tip or blue long-range tip. Downstream injectors only pull chemical when line pressure drops, so a standard high-pressure nozzle will stop the draw.

The injector assembly comes with quick connects installed and 4 feet of chemical draw hose with a strainer on the end. Drop the strainer in your soap container and you're ready to run.

Yes — the injector may arrive plumbed backwards for your setup. Swap the fittings on the injector body so the flow-rate arrow points downstream, away from your machine, and it will draw correctly.
