I bought this to connect my 22mm pippes from my heating system to the underfloor heating manifold. After putting the whole system back in pressure, it leaked (and this was not the weld). This was due to this connical shape that did not go inside the male section on my UFH manifold.
Not really sure what this connector is designed for but this conical shape does not seem right (or I have not understood how ot is supposed to work)
Needed in a hurry and Toolstation came to the rescue once again, instock and a great fit. Local store had it on the counter before I arrived 15 minutes after ordering on the app and it was a quick pickup, fitted and leak solved in under an hour including the drive there and back!
