Hi
I was wondering if anyone could help ?
I am in the process of fitting Danfoss RAS-C2 TRVs and lockshield valves to my Myson radiators.
With the radiator removed from the wall, I cleaned out the 1/2" BSP tails on the radiators using a round wire brush. This allowed me to remove the old remaining PTFE tape together with some slight rust.
I first inserted the new radiator tails in the ends of the radiator dry to gauge how far it they would go when tightened up.
On removing the tail I then applied 6-7 wraps of Loctite 55 to the lower half to the radiator tail crossing the threads as I went, rather than following the thread grooves, as per the Loctite 55 instructions.
I started to make up the tail using a 16mm ring spanner - approx 8" long. With about 3 threads to go I needed to switch to a 10" Bacho adjustable wrench to tighten the tail all the the way up. It took a bit of force, but nothing which felt excessive, albeit this is first time that I have fitted radiator tails.
I have yet to refit the radiator and fill with water which will be the ultimate test, however I happened to notice that the nut of the radiator tail bound slightly when it was rotated around the tube of the radiator tail, which was not the case before I make it up ??
Is this normal / to be expected ?
Cheers
