got a -12 industrial interchange coupler. is this the right dust cap for it?

Question by: Hank W on Dec 13, 2025, 4:10 PM

For a -12 coupling size, this cap matches that size callout and is part of the 5600 Series Industrial Interchange style. It is a female compression end and is meant to cover and protect the mating quick disconnect end when it is not in use.

does this cap work with the standard industrial interchange couplings or is it only for specific eaton fittings

Question by: Keith B on May 9, 2025, 8:30 AM

The 5657-12 conforms to ISO standard 7241/1 Series A, which covers the dimensional spec for Industrial Interchange couplings. That means it should fit any coupling built to that same standard, not just Eaton branded ones. The -12 coupling size with a 0.75 end size is what you want to match up on your end.
