Heavy fittings show there is plenty of copper used in their manufacture and built to last. You know it a good one as soon as you pick it up. M Press jaws crimp this fitting perfectly onto 22mm pipe for a leak free joint. When you pipe up with press fit, it looks really good too. I like how Peglar Xpress fitting slightly grip the pipe when first pushed on so stay nicely in place when confirming a run unlike some of the others that are completely loose until crimped.
Not had one fail yet, good m press fittings, would buy again
