Air compressor quick coupler that doesn't leak

[stuckmotor]

Several of the cheap quick couplers on my air compressor hoses and air tools leak. Is there a brand or type that seals better than the rest? Is there a trick to making them seal?

Genuine Milton couplers are superior. Keep them clean, both male & female.

Hard to go wrong with Milton, at least in the past, since all mine are at least several years old.

If at one time they did not leak but now they do then try cleaning them up and put a little lite oil on them. That works for the one I have. They are all older.

I've got some USA couplers from the 1950's (from my dad, I'm not quite that old) that don't leak. A little silicone on the seals does wonders. Some new ones, Harbor Freight grade, do leak. Hmmmm. You gets what youse pays for (sometimes)

We have a lot of the HF quick couplers and none leak.

I have both HF and Walmart (Campbell Hausfeld)quick couplers and none of them leak and they mix/match very well. I guess I am just lucky to have not picked up any with a defective seal.

Thanks everyone. I think I'll try: cleaning, oiling, Milton, in that order, until they quit leaking.

If you do any spray painting stay away from oil and silicone. sometimes two male fittings the same style, one will leak & one will not, maybe thats where cleaning comes in.
