I'm in the process of replacing a heated wet towel rail but forgot to recover the original tails and examine how they were seated before dumping the old rail.
After showing pictures of the existing lockshield type valves that are still attached to the flow and return pipes the plumber merchants sold me new tails which I believe are called "Standard Tails" (http://gasboilerforums.com/changingaradiator.html).
The tail has a flange that sits within the threaded rim of the lock shield and is held down by the large nut. There are no rubber o-rings around the flange, in the nut or on the lockshield valves. There were no rings or olives when I removed the original fittings and no signs of leaks.
When the tail flange is pushed down on to the rim is the seal purely bare metal on bare metal or should I use some sort of sealing compound within the valve seat and/or on the flange and PTFE on the external thread of the valve seat?
Is it ok to reuse the existing valves that are still attached to the pipes?
Thanks
