"Seemed like a good idea at the time but......... Purchased one of these and unfortunately it's been a bit of a horror. On my purchase, the tap connector part is screwed into the body of the fitting using hex headed adaptor (not brazed as on previous examples I've used and not the same as shown in the item photo) At the bottom of this thread is an o-ring which is very easily damaged due to movement in the main body when tightening. Been chasing leaks (o-ring and thread) with this for sometime now finally replaced with standard bent tap connector and isolating valve further along pipe. Wouldn't want to try another of these.
