Part Number: AW-8400-0021
Brand: Mi-T-M
Category: Pressure Washer Accessories
Type: Mi-T-M Low Pressure Detergent Injector – Adjustable

The Mi-T-M Low Pressure Detergent Injector (AW-8400-0021) is a professional-grade chemical injector designed to apply detergents at low pressure for effective surface cleaning while protecting the pressure washer pump. By introducing chemicals downstream, this injector allows detergents to dwell on surfaces longer before high-pressure rinsing, improving overall cleaning performance.

Constructed from durable brass, this injector is rated for up to 4,000 PSI and supports 3.0–5.0 GPM flow rates, making it compatible with many residential and commercial pressure washer systems. An adjustable chemical draw allows precise control of detergent concentration, while the clear, pliable detergent hose provides easy visual monitoring of chemical flow.

Equipped with quick-connect fittings, the injector installs easily and integrates seamlessly into existing pressure washer setups.
