Mr Fardell tested the product on “difficult and very loose” radiator tails after “masses of PTFE tape” failed to work; one simple application of LOCTITE® 577 produced a totally leak-tight join in seconds.
Recently, Mr Fardell was asked to specify, source and fit thermostatic and lock-shield valves on seven radiators in a domestic property. However, the task proved not as straightforward as it first appeared.
“Upon removing the existing valves I found that the original installer had seriously over-tightened the compression fitting connections, with the result that the 10mm copper pipe had been deeply grooved at the biting/sealing point of the olives,” he says. “I also noticed that the new valve tails were a very loose fit into the radiators”.
