How do I service female QD air chuck ?

[SC Maintenance]

My little pancake compressor has two air chucks and one leaks a little sometimes. If I cycle the other part in and out a couple times and it stops. So I assume its dirty / sticking. Is there a type of lubricant or cleaner I can spray in, or soak it in. I assume its a nitrile o-ring? Maybe WD-40 or should I use something like CRC electrical connector cleaner?

If I can't fix it - is there a good brand of these anymore. Used to Milton I think? They still exist?

Funny you should bring this up now. I had an 18 year old Milton QD coupling fail in June and replaced it with a new Milton part. Cheaper on Amazon, but available at a Northern Tools B+M store if you need it today.

I have had luck disassembling some of mine and cleaning them.

I've sprayed sticky ones with WD40. Seems to clean and loosen them up. If that doesn't work get a new one. They cost about $5.00 and not worth screwing around with in my opinion.
