SKU B07MGGFZ9B Category


Get heavy-duty performance from your pneumatic tools and equipment with these 1/4 in NPT brass female industrial air couplers from SUNGATOR. The 10-pack includes quick connector fittings constructed with solid brass for maximum durability on the jobsite or in the garage.

Made of Solid Brass for Superior Strength

These air hose fittings feature a high-quality brass construction that stands up to demanding industrial applications. Solid brass resists corrosion, abrasion, dulling and scratches better than lower-cost metals like aluminum or zinc. You’ll enjoy reliable connections and leak-free airflow shift after shift.

6 Ball Bearings for Secure Coupling

Each 1/4 in female coupler utilizes 6 steel bearing balls to create a tight, dependable seal when connecting air hoses and equipment. The 6 ball design provides a more heavy-duty grip than 4 ball models. You’ll have the peace of mind that your attachments and tools will stay safely connected under pressure.

Knurled Sleeve for Easy Handling

A knurled outer sleeve gives you a textured, non-slip grip on the couplers for quick connects and disconnects. The knurling makes it easy to attach hoses and tools without the need for wrenches or other tools. It also helps prevent accidental disconnects.

1/4 in NPT Threads for Versatile Use

These industrial air fittings feature the widely used 1/4 inch NPT threads. This standard sizing allows them to connect with air hoses, guns, nozzles, inflators, air compressor output, and pneumatic equipment. If your air tools have 1/4 in NPT ports, these will match up perfectly.

Rated to 300 PSI Max Pressure

Never worry about these female connectors blowing off or leaking. Their heavy-brass construction and multiple interior O-rings are engineered to hold up to 300 PSI of max working pressure. Use them for high-demand garage and shop tasks.

Wide Compatibility

These 1/4 in couplers are designed to connect with industrial M-style and automotive D-style air plugs – the most common types of pneumatic male connectors. You’ll get leak-free connections with a wide range of air tools from impact guns to grinders to nailers and more.

Handy Storage Case Included

The industrial air couplers all come neatly organized in a durable plastic carrying case. The case keeps the fittings organized and protected. You’ll always know right where to find the size you need and won’t have to hunt down loose fittings in a drawer or toolbox.
