The BE 85.300.105SBEP is an industrial-grade 3/8" Quick-Connect (QC) male plug featuring 3/8" Male NPT (MNPT) external threads. Forged from high-grade stainless steel, this plug is engineered to provide a rust-proof, high-pressure connection point directly on your pump outlet, spray gun handle, or manifold. Unlike standard steel fittings that can pit and corrode over time, the stainless steel construction ensures a smooth connection and a long service life, even when exposed to harsh chemicals, detergents, or salt-water environments. Rated for pressures up to 6,000 PSI, it is the top choice for hot-water and heavy-duty commercial pressure washing systems.
