Positive Shut-Off Control. High-Pressure Rated. Built for Professional Systems.
The 3/8" Quick Connect Ball Valve Kit (Part # 85.300.044) is designed to give operators instant on/off flow control in high-pressure washer systems. Rated up to 5,000 PSI, this heavy-duty ball valve kit allows you to safely stop water flow at the hose, gun, or accessory level—without shutting down the entire machine.
Featuring 3/8" quick connect fittings on both the inlet and outlet, this kit installs quickly and integrates seamlessly into professional pressure washer setups where control, safety, and efficiency matter.
Built for Pressure, Heat, and Control
This ball valve kit is rated for temperatures up to 82°C / 180°F, making it suitable for both cold and hot water pressure washer applications. The internal seal and Viton O-ring provide excellent resistance to heat, detergents, and chemical exposure, ensuring long service life and leak-free operation even under demanding conditions.
Unlike standard inline couplers, the integrated ball valve allows the operator to instantly shut off flow—ideal for changing nozzles, surface cleaners, or accessories without returning to the machine.
