“This didn't work, It doesn't tighten down enough to close the olive, water leaks through the fitting despite using the rubber ring.Not at all suitable for connecting to polyorc pipe. I found one at a merchants with a full olive that did the job perfectly. Total waste of money buying this one.”
“Brought these fittings as have grey plastic pipework and want to be prepared for any problems in the future. Good price and speedy delivery. Excellent service .”
