Connection to Imperial Copper

When connecting to 3/4" imperial copper Hep2O® offers a special 'O' ring straight adaptor (HX3A/22) which accepts 22mm pipe at one end and 3/4" imperial at the other end.

1/2" & 1" imperial pipes can be connected using standard Hep2O® fittings, as the outside diameters are virtually the same as 15mm & 28mm metric pipes.
