ptfe tape or no ptfe tape?

[Rob876]

What's best on compression fittings - ptfe tape? A compound? Just the olive?

 

[Pickwickpick]

I just use the olive, if fitted properly you shouldn't need anything else imo. Then there's the numptys that put ptfe on the thread of compression fittings which bugs me!

Search PTFE in the search area top right.

I always use a few wraps of ptfe round the olive

I always use paste. It acts as a fine sealant and also lubricates, so will help when you compress the joint.
Ptfe wrapped over olive a few turns will help seal well, but the tape gets cut and I would then be wary that water can still passs the olive

Didn't used to bother with PTFE until we started getting some olives made of crap material (the first of the Chinese I think), so started then.
Always use if having to remake a joint using old olive, although since getting a bona fide olive splitter I tend to fit new olives if I can.
Equally mystified why someone would put tape on the threads of a comp joint.

Those who put tape round the threads don't understand how the fitting seals.

OGM, just remember it's not the Chinese at fault. They make perfect kit - WHEN asked to do so and WHEN allowed (through price) to do so. It's carp because BUYERS do not wish to pay for quality.
It's no different to our job. When a customer pays for a good job they get a good job. When they pay peanuts they get rubbish!

Probably expert bathroom installers.

Some folk know that ptfe tape is called “thread sealing tape”, so they use it on threads, - all threads.

Some say that a turn or two of tape on the threads acts as a lubricant and makes it easier to tighten the nut.

Agreed. If stuff is supplied on basis of price only, that is what happens. What got me was the dodgy olives came from my normal supplier who is usually quality aware.
Not worth fitting cheap stuff. Just been out to sort an expensive Mira shower with its filter blocked by shards of chrome plating from the shiny but cheap compression fittings used on the pipework to it. Not my install, I hasten to add.

And some people are idiots

Only will make it tighter to turn I would think

When did a nut become difficult to tighten?

 

[Harvest Fields]

The same time it was standard practice to put PTFE on them.

That is the cod of being on a forum, just takes one sole to do an answer to a thread and it become a red herring.

 

[Harvest Fields]

I’m going to makeral of you laugh with this one.

I could go on and talk a lot of pollocks.

 

[Harvest Fields]

Stop skate in around the issue would you.
