The 3/8″ Female NPT × 3/8″ Quick-Connect Plug Adapter is a heavy-duty fitting designed for high-pressure washer systems and pneumatic air lines. It converts a 3/8″ female NPT thread into a 3/8″ quick-connect plug, allowing fast, secure, and leak-free connections between hoses, spray guns, and accessories.
The adapter is manufactured from solid brass or durable plated steel, providing strong resistance to corrosion, wear, and high pressure. Its tapered plug end with ball-lock design fits securely into a female quick coupler, while the threaded base connects easily to standard NPT fittings without special tools.
Designed for demanding applications, the adapter supports working pressures up to 5,500 PSI, making it suitable for both gas and electric pressure washers, as well as industrial pneumatic systems.
It is commonly used for quick connection of spray guns, foam cannons, wands, hose extensions, and air tools, allowing fast equipment changes while maintaining a tight, leak-proof seal.
