Attaching nut and olive on a radiator tail

Question

I've got a new radiator tail. The nut and olive slides onto the tail. How do you stop it sliding off? Is it just a matter of packing the olive with ptfe tape?

Hi,

The nut and olive will squash onto the pipe once you tighten it up. You don't need PTFE tape

Ricky · Answer

You put it on loose .and it pushes back whe you push the tail in the connection then tighten into up

Patrick · Answer

John you need to tighten the nut onto the body part of the valve which will compress the olive to the tail then you can put on some ptfe tape and remake the joint

Craig · Answer

You push the pipe on to the tail as you tighten the nut up as long as the tail is long enough

Iain · Answer

The Olive sliding up and down the pipe is okay. Just make sure the pipe is pushed home into the hole in connector and while holding the pipe home,  tighten nut which will squeeze the Olive around the pipe and seal the joint.
PS: Wrap  three turns of PTFE tape around the thread on the connector before screwing the nut home.

Hi, just a case of tightening the nut once it is on the tail, not forgetting to put the olive on after, you have put the nut on the tail. Tightening the nut will compress the olive. Regards Roger

Mario · Answer

The best method is to smother the olive with jointing compound before compressing the olive with the nut.

Phillip · Answer

Just tighten the nut/,olive to the radiator
Valve the olive compresses around the radiator tail,should be a tightly fitting.

John · Answer

Hold in the pipe into tail whilst tightening up the nut and Olive will tighten up with the nut into the tail

Colin · Answer

Theoretically, toy should not need to put PTF on to a compression joint, if the fitting and olive are both the correct size and fitted correctly they should not leak, as when compressed the olive creates a seal.
