50 of the wire water meter with a large head to undertake, the joint wire mouth how much? Is it 50?
Water meter is inside diameter, and PPR is outside diameter. The purchase is to indicate to the distributor that it is 50 of the water meter mouth or directly with material in order to fit.
50 meter socket is 50. But the name of PPR is different from that of water meter.
Buy 2 inch PPR connector can be inside the mouth!
