Compression fittings

[Matt0029]

Dab of V2 on shoulder of olive where it meets the nut. Gets smeared round as you tighten.

Do you paste the olive before you tighten on to the pipe? I occasionally PTFE d the olive but was time consuming backing it off after tightening to wrap around. Thanks

Thanks, do you use it every time you do a compression fitting?

Yep every time , personally only paste the pipe in front of the olive and insert this avoids excess paste entering the pipe causing blockages

Yes. And if I PTFE then I do it before any tightening. Not sure why you would remove to tape - time consuming as you say and if anything likely to introduce leaks.

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

I put on the nut then olive then fitting. And wrap the olive in situ. Once the olive is taped it won't go anywhere.
Out of interest I was looking for pictures of compression joints and tape and found this on diydoctor.com
SMFH!

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

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.
