Model: 100827
Category: Pressure Washer Parts & Accessories → Chemical Injectors
Type: GP Adjustable High-Draw Acid Chemical Injector – 1.5 mm Brass

The GP 100827 Adjustable High-Draw Chemical Injector with Acid Kit is a genuine General Pump (GP) OEM downstream injector designed for pressure washer systems that require adjustable detergent or acid-based chemical application. Installed downstream of the pump, this injector prevents corrosive chemicals from passing through the pump while allowing efficient detergent or acid injection into the water stream.

Note: For proper injector performance, pressure washer hose length should not exceed 100 feet, as excessive hose length can reduce chemical draw capability.
