Why Professionals and DIYers Choose the BE Power Equipment Pressure Washer 3/8″ Low Pressure Chemical Injector Kit

Contractors and cleaning pros rely on this chemical injector kit because it keeps corrosive products out of their pumps and simplifies detergent application. It’s commonly referred to as a “downstream injector”, “pressure washer soap injector”, or “chemical siphon kit”—all terms customers frequently search when looking to add soap or sanitizer to their washing jobs. With dependable flow and a simple setup, this is a go-to add-on for users running pressure washers in the 2–3.5 GPM range at up to 4000 PSI.

This injector is especially useful when working with a black soap nozzle (not included), which activates the low-pressure mode needed to draw chemicals. It’s one of the simplest and most reliable ways to get chemical flow without needing electric pumps or extra fittings.
