3/8″ Quick Connect Coupler, Brass, Male NPT, High-Pressure

SKU: NHP509

$2.10

This quick coupler plug (also referred to as a male nipple or fitting) is designed for fast, secure, and leak-free connections in pneumatic systems and pressure washer setups. Featuring a 3/8″ male NPT thread and a 3/8″ quick-connect body, it is constructed from hardened steel or brass with gold-colored plating for durability and corrosion resistance. Rated for 300 PSI (air tools) up to 5,500 PSI (pressure washers), it is ideal for compressors, spray guns, and high-demand pneumatic equipment.

The Quick Coupler Plug with male thread is a versatile fitting commonly used in pneumatic workshops and high-pressure cleaning systems. Its external threaded design allows easy installation on hoses, spray guns, compressors, and pressure washer equipment, while the quick-connect profile ensures compatibility with standard industrial couplers.

The 3/8″ version with male NPT thread keeps a standard quick-connect body while adapting to larger 3/8″ ports, making it suitable for connecting standard hoses to tools with higher airflow requirements. It can also be used with threaded accessories, as adapters with 3/8″ male NPT to 3/8″ quick-connect plug configuration allow conversion of threaded connections into quick-connect fittings, which is useful for attaching nozzles, lances, and pressure washer wands.

Built for durability and reliable sealing, this plug is suitable for compressed air systems, pressure washers, and general industrial applications where fast connection and secure locking are required.
