Quick connect

[Marv]

The brass quick connect that I have been using, mainly with x-jet, suddenly will not lock on. Tried different ones, and was not attached to handle, so not a pressure issue. No sign of sticking or debris. Moves freely, as usual, but will not close over inserted fetting.

It would be cheap to replace it, but I want to understand and fix on job site if it were to happen in the future.

any ideas?

Inspect the o-ring for wear. Usually replacing the worn o-ring will cure leaky fittings and difficult reconnects. I always carry spares I buy Viton hitemp o-rings by the hundreds.

I suspect the quick coupler plug is galled where
the o-rings ride on it, replace the plug, if the
socket seems to have a lot of wear replace it also.

If you'll look close at the plug it will be indented from the balls on the QC,for a quick fix in the feild take a pair of pikers and clamp,twist around where the burr's are.

Interesting post, considering that I just came in from doing PM on my fittings! In addition to the above, you may want to confirm that the plug is the problem by trying the same coupler with a good plug - if that works odds are that the plug is the culprit. You may also want to be sure that the coupler has no sand or other debris embedded.

I run all stainless steel plugs,I use stainless steel QC's at the end of the psi hose and on the downstreamer,all others are bass QC's with S.S. Plugs.I hardly ever have any trouble with plus or QC's,also think when useing S.S QC's with bass Plugs it will eatem up,as the S.S balls digs into the softer metal,the Bass QC as a harder time digging into the S.S. plug.

It is free of any debris (visible). I also tried with two new male fittings, ssteel. It is brass, I used at the end of wand.

Bigboy, I think you may be onto to something - brass couplings and SS plugs. I think I will give that a try myself.

I have noticed that my SS plugs do get "narley" pretty quickly, causing a 'disconnect failure' without much warning.
