Radiator tails weeping

[kristeva]

Hi all,

I fitted my first rad the other day and unfortunately both tails are weeping. Whilst holding the tail in my left hand I wrapped ptfe between 15 and 20 turns clockwise. I screwed them in with my radiator spanner as far as they would go, not quite up to the last thread though.

Im going to drain the system (its only a couple of rads) and try again. I guess the options are to try and screw them in a little further? Or Shall I start again and try more turns or slightly less turns and make sure the tail is fully screwed in up to the last thread. Its a cast iron radiator.

Any tips appreciated.

While draining down the rad, why don't you cut the fixing bracket back and hide it inside the cast iron rad.
It's 3 column so you can hide it behind the first or second column.

Also, the connections where the tails connect to the rad are brutal. You might want to clean them out with screwing a 1/2" thread into them a few times to clean them out a little. Lubricate the female thread and then screw in your tail.
The cast iron tapping doesn't allow the tape into thread all that good due to its roughness.

When you remove the tail, I doubt there will be any tape in the threads
