A pressure washer without soap injection means mixing chemical by hand or skipping the pre-treatment step altogether — both of which slow a mobile detailing, fleet washing, or building maintenance crew down. The Hydro-Tek AC340 Downstream Soap Injection Kit bolts onto a Hot2Go pressure washer and lets the operator switch chemical application on and off from the gun, without ever touching the pump.
Built For
- Fleet and truck washing — applying degreaser or detergent before the rinse pass without stopping to hand-mix
- Building and concrete cleaning contractors — switching between plain rinse and chemical application mid-job
- Mobile detailing operators — consistent soap application across multiple vehicles per day
- Any Hot2Go pressure washer owner upgrading from manual chemical application to true downstream injection
Because the injector introduces chemical downstream of the pump, detergents never pass through the pump itself — protecting seals and o-rings from the corrosive wear that upstream chemical injection can cause over time.

Frequently Asked Questions
What is included in the AC340 kit?
The kit includes the downstream injector body, a chemical pickup hose with strainer, a soap nozzle, and the quick-connect fittings needed to install it between the pump and the high-pressure hose.
Does downstream injection protect the pressure washer pump?
Yes. Downstream injection introduces chemical into the water stream after it leaves the pump, so detergent never circulates through the pump itself. This reduces chemical wear on pump seals compared to upstream injection systems.
Can I control the soap on and off from the gun?
Yes, that is the main advantage of a downstream kit like the AC340 — the operator can switch between rinse and soap application from the spray gun without adjusting anything at the machine.
Is the AC340 compatible with any pressure washer, or only Hot2Go models?
The AC340 is built for Hydro-Tek Hot2Go pressure washer systems. Confirm your specific model and pump configuration before ordering to ensure correct fitment.
