MLCP Fittings dripping

[jackyp1234]

Has anybody had any experience of MLCP fittings leaking? I’ve used tweet top fittings on a few decent sized jobs and had zero issues, however I’ve just been to a job I’ve done and 3 fittings had a very small drip on them, crimp gun has been calibrated etc and pipework has been correctly deburred,

Has anybody else had any problems?

Cheers!

What pipe and fittings and size ?

Cheers for the reply.

25mm and 20mm, worrying because we’ve just done a big job that’s about to be boarded next week, pressure tested to 5 bar and all seems fine just worried a small leak will happen in the future!

That’s what I wanted to hear, yeah using the u profile jaws, it’s in abit of a crawl space which was awkward to work it so I’m wondering if it’s maybe dislodged one of the o rings pushing the fittings on, I love using the stuff so was hoping no one else had issues with the fittings etc! I’ll get a pic next time I go, it’s a very small drip. Not a constant drip more just a small build up on the fitting if that makes sense! Was just abit paranoid about the big job we’ve just done in it but should all be fine. Thanks for replying mate

Just to put your mind at rest I did a test removed all the oring and pressure tested upto 10 bar not one drop held fine

So yes sounds like it’s dislodged one of them and it’s not in fully or something else

You sure it’s not condensation?
