The Quick-Connect Female Socket Adapter 3/8″ NPT is a heavy-duty fitting designed for high-pressure washer systems and pneumatic air lines. It allows connection of a 3/8″ male NPT threaded accessory to a quick-connect socket, providing a secure, leak-free, and easy-release connection for professional use.
Built from solid brass, the adapter offers excellent resistance to corrosion, rust, and high pressure. Unlike aluminum fittings with brass coating, the full-brass construction ensures greater durability, longer service life, and reliable sealing in demanding environments.
The coupler uses a ball-lock quick-connect mechanism, which locks the plug firmly in place and releases instantly when the sleeve is pulled back. It supports working pressures of approximately 4,000 to 5,500 PSI, making it suitable for pressure washers, spray guns, foam cannons, wands, surface cleaners, and industrial pneumatic tools.
This fitting is commonly used as a 3/8″ female NPT quick-connect coupler, compatible with many high-pressure and M-style air systems.
