Product Questions & Answers

got a worn out quick disconnect on my air compressor setup, would this male half with the 1/4-18 npt fit right in as a swap?

Question by: Roger W on Dec 30, 2025, 3:46 PM

It matches up with standard industrial interchange designs under MIL-C-4109, so yeah, it'll plug into compatible female halves for air applications, especially if your current one's from Danfoss or Eaton Hansen in those series.

Will this plug fit standard air hose fittings?

Question by: Howard A on Aug 14, 2025, 7:52 AM

This male half quick disconnect is made to the MIL-C-4109 industrial interchange standard, so it should work with any female coupler also made to that spec. Just make sure the size (-04) and thread (1/4-18 Male NPT) are compatible with your existing setup.
