good product, does what it is supposed to do, nothing more, nothing less.
I needed two of these. Having cut all the pipes and soldered them I connected them up and they both leaked. Tried taking everything apart a few times and they still leaked. The problem is that the washers are too spindly. They don't fit snuggly to the nut or the flange at the centre so they move around and any slight sideways movement produces a leak. I had to throw everything away and start again with decent fittings. I couldn't return them as I had soldered them. It is not the cost which bothers me so much the time it wasted and the extra trip to get more fittings; a half hour job ended up taking half a day. One star is because I can't give zero and they are cheap to buy!
Accurate piece of engineering
This product is ok. Only got it to show someone that the new patent pending product called ConnFix connector would be much easier to use. ConnFix Connector is the future
