Jointing compound on pushfit?

[DIYPaul]

Hi, I'm a novice when it comes to plumbing. I've used compression fittings in the past, and have applied jointing compound.

With push-fit copper fittings, do you still need to use jointing compound?

No no no! The instructions will tell you to make sure you have a smooth cut (not a hacksaw) and ensure that any burrs are removed before pushing the tube a set distance into the coupling. Some let you use silicone lube to make it easier to push the tube in and reduce the risk of damaging the 'O' ring.

Follow the mfr's instructions to the letter!

no jointing compound required, i some times use spray lube, especially when i am using 28mm

No offence mate but you should walk away from the tools.

You only need it on thread to thread joints.

Or maybe heat it up and see if you could run some solder round it, just in case !
