are these Aeroquip couplers repairable?

[Mike Van]

I have a bunch of these that won't seal any more. Anyone know if these's an o-ring inside that can be replaced? They've gotten kind of $$$$ to just chuck out -

Welcome to the world of Chinese $hit. Even the expensive ones only last a little longer.

Most can be serviced. That looks like a plug vs the coupling? Mine have a rubber washer, I flip them over and even clean them once in a while.

That end you may be able to replace the internal seal by just depressing the inner poppet. Small arbor press or maybe a C clamp or vise with a small dowel pin or bolt?

Do you have a PN? There might be a rebuild kit I could reference for you. Is it an aero quip part. Photo of the female coupler?
