Compression fittings

[Matt0029]

Have noticed my success rate with compression fittings fall over the last year or so. Am getting a few that weep. When I back to nut off to have a look the olive isn't over tighthed and I always clean the pipe first. Wondering if anyone else has noticed this whether it's just me or the quality of fittings has decreased. Have recently started using V2 plus on the olive. This seems to give a perfect joint all the time. But obviously adds time in as have to back the nut off after tightening to apply.

The male/female irons at our local independent now weight not much more than half what they used to, and fitting faces/threads are variable to say the least.

Bloody auto correct, was supposed to read

I used to do it as an apprentice (How i was shown), to prevent the olive moving up and down.

It does 😀

I'm a rank total amateur but use a thin layer of Fernox LSX on the pipe, push on the olive then another thin layer. Also now when I remember a dab of grease on the threads to get a better feel for the tightening of the nut as I've l
poor hand strength. Never had one leak but that's statistics.

Thanks my soldering is pretty much 100 percent. I say touching wood 😅. But have started to get hassle with compression fittings will definitely start of the paste routine! Thanks for the advice

Quality is dropping off for every day fittings unless you use conex , kuterlite and the like

I used to use the regin paste but now use this.

What’s the texture like comparable to jet blue ?

So the Kuterlite is top quality Pegler and you can get them from Screwfix. See Screwfix also stock Pegler's Endex end feed fittings for soldering. For those with an Xpress tool would you also do Pegler VSH?

All decent quality kuterlite, pegler, conex for compression fittings, prefer Geberit for crimping.

When fitting new compression fittings I never use PTFE or paste but after pushing the pipe fully home I then pull it back a few mm before tightning up.

That's interesting, can you say why?

 

[John.g]

I just feel that the olive can do its job properly without the pipe end being stopped and restrained from moving inwards with less sealing force on the olive end.

 

[Matt0029]

Do you also use the paste on olives on gas?

 

[king of pipes]

I do obviously had to be suitable for its use with gas. Kop
