This hi-lo gun assembly is intended for use in high-pressure 2-step washing systems where you need to switch quickly between a low-pressure presoak/acid and a high-pressure alkaline soap or rinse without changing tools. The design combines a long 60" stainless steel lance for extended reach on tall trailers and equipment with a premium swivel hi-lo nozzle so you can move efficiently around tractors, box trucks, tankers, and heavy equipment.
Key features and benefits
- Premium single-barrel hi-lo gun assembly optimized for professional fleet and commercial pressure washing.
-
Built for 2-step washing: use one tip for high-pressure rinse and one hi or low-pressure tip for soap application (tips sold separately), allowing fast step changes while keeping chemicals out of pumps and coils.
-
60" stainless steel lance provides excellent reach for trailers, cab roofs, vans, and equipment while maintaining precise spray control and long-term corrosion resistance.
-
Premium acid-resistant trigger is engineered to handle low pH presoak and other aggressive chemicals common in touchless fleet washing without premature wear.
Connections and compatibility
-
Inlet: 3/8" male plug with stainless steel hose swivel for smooth hose management and reduced operator fatigue during long wash sessions.
-
Outlet: 1/4" male socket to accept standard quick-connect rinse and soap tips used on most commercial pressure washer setups.
-
Stainless steel hose swivel at the inlet minimizes hose twisting and kinking, improving maneuverability around tractors, trailers, and wash bays.
Nozzle and protection details
-
Includes a premium swivel hi-lo nozzle, allowing you to quickly toggle between high and low pressure for 2-step chemical application and rinse.
-
Comes with two rubber nozzle protectors (1 black/red, 1 black/gray) to help shield tips and surrounding surfaces from impact, ideal for working close to painted truck panels, mirrors, and accessories.
Ideal applications
-
Perfect for mobile fleet washing, truck and trailer washing, bus and equipment washing, and other commercial high-pressure cleaning where 2-step chemical processes are used for touchless results.
-
A strong upgrade for operators who want a long-reach, stainless steel, acid-ready hi-lo gun assembly that integrates seamlessly into existing professional pressure washer and 2-step systems.
