The 16-piece set includes everything you need for quick, leak-free connections between your air compressor and tools.
The 1/4 NPT quick connect couplers let you swap tools in seconds - no more struggling with stubborn connections mid-project.

Built from carbon steel with nickel plating, these fittings handle up to 300 PSI and stand up to professional shop use.

The swivel design prevents hose kinking, and the deep-knurled sockets ensure secure ball-lock connections every time.
You get a perfect balance of male and female plugs and couplers that work with most air tools - nailers, blow guns, impact wrenches, you name it.

The quality is industrial-grade but priced for DIYers too.
No more air leaks wasting your compressor's power or hunting for the right fitting in the middle of a project.

This complete kit organizes your air tool setup and makes everything work smoother and faster.
