Maximum Pressure. Full Flow. Stainless Steel Control.
The 3/8" Female NPT Stainless Steel Ball Valve Kit (Part # 85.300.046S) is built for extreme high-pressure applications where durability, safety, and unrestricted flow are critical. With an impressive 7,250 PSI pressure rating, this full port stainless steel ball valve kit is designed for professional and industrial pressure washer systems that operate at the highest performance levels.
Featuring 3/8" FNPT inlet and outlet connections, this valve kit is ideal for threaded, hard-plumbed installations where strength and reliability matter most. Whether used in hot water pressure washers, industrial cleaning systems, or custom-built high-pressure setups, this kit delivers precise shut-off control without sacrificing flow.
Built for Extreme Pressure and Demanding Environments
Constructed from high-grade stainless steel and sealed with Delrin seals, this ball valve is engineered to withstand intense pressure, repeated cycling, and harsh operating conditions. The full port design ensures there is no internal restriction, allowing water or fluid to pass through at full volume—reducing pressure drop and protecting pumps, unloaders, and downstream components.
Rated for temperatures up to 82°C / 180°F, this valve is compatible with cold and hot water systems and suitable for many cleaning chemicals commonly used in commercial and industrial pressure washing.
Why a Full Port Ball Valve Kit Matters
Full port ball valves are preferred in high-pressure systems because they:
Maintain full system flow with zero restriction
Provide instant on/off shut-off at the point of use
Reduce strain on pumps and pressure-regulating components
Improve safety during hose, gun, or accessory changes
Offer long service life in demanding applications
This makes the 85.300.046S Ball Valve Kit an excellent choice for industrial cleaning, fleet washing, equipment maintenance, and high-pressure system builds.
