Leaking Radiator tail pieces

[Covdad]

Hi

Just fitted a new towel radiator in my en-suit.
Unfortunately it's leaking from the tail piece you screw into the bottom of the rad. I wound round about 4 layers of PTFE tape too. I have since taken it off and wound round 8-9 layers and it screwed up nice and snug but still leaks from both sides and definitely from that join.
I watched a couple of YouTube videos and they screw the tail piece all the way until it stops but mine doesn't bottom out if I carried on the nut would fall into the rad so it's only sealed with the tape. Would a paste be worth adding?.

Way more ptfe double what you have used.
Better still use loctite 55 yet to see a rad tail leak with that.

Thanks
Do you still use the PTFE or just the Loctite?

You can just use ptfe, you can just use loctite, not recommended mixing the 2 if that’s what you’re asking?
