JOEJET Downstream Injector for Pressure Washer — 3/8 Quick Connect, 10 ft Siphon Hose, 3-5 GPM, Up to 3200 PSI

Boosted Detergent Delivery for Your Pressure Washer

JOEJET's Downstream Injector uses a siphon principle to draw detergent from a separate container, enabling targeted cleaning across driveways, cars, roofs, and walls. The design supports safe and effective delivery, with orientation of the arrow guiding flow for proper operation.

Real-life use often involves tackling oil-stained driveways, washing a dusty car, or refreshing a weathered fence. The system is built to withstand routine outdoor cleaning tasks, while helping you keep the pump protected by preventing backflow when installed with the 3/8" quick-connect setup.

Built to last, the injector pairs brass construction with stainless steel components to resist chemical exposure and endure high-pressure tasks. It handles pressures up to 3200 PSI and a flow range of 3-5 GPM, making it a versatile add-on for many pressure washing projects.
