Guys, i see alot of plumbing where people have put ptfe on compression fittings? i never have used it, but are you meant to or not?
it is only of benefit to wrap PTFE round an olive if you don't want it to leak.
It seems to me that professional plumbers like to boast that their joints never leak so they have no need of it.
My experience suggests otherwise.
You never need to use PTFE on a compression fitting, it is something done by DIYers, Not tradesmen have a look here http://www.yorkshirefittings.co.uk/media/training/TF_2008-12-19/pegler-yorkshire/shell-web.html section 4, no mention of PTFE been required
We know what the manufacturers say. They tend not to give guidance on fittings that are less than pristine. As I said the general rule is against using PTFE or sealing compound such as Jet Blue..but then what happens when you obey the rules as laid out by the manufacturer, and your joint leaks. You dismantle it and remake it...it still leaks...then what do you do.
In the real world every plumber has at some stage either reached for the PTFE or more likely the Jet Blue to seal the b**er up. Now and again its just what you have to do to get the job done.
I really don't care if anybody disagrees with the practice. Thats what happens. It works.
I know a big commercial plumbing company that gives verbal warnings to its staff if they don't use Jet Blue on ALL compression fittings. It saves them a lot of callbacks, which is why they do it, I don't agree with their stance, but so what, they pay the wages, they call the shots.Alfredo
I don't believe there was ever a golden age when joints never leaked.... perhaps the quality of the stuff we buy now isnt as good and there are more leaks being left ....
