HKU two-part radiator connection systems with 1/2″ internal thread

The two-part HZ radiator connection systems with “½” female thread made of brass is suitable for transition fittings preferably for plastic multilayer pipes. It can be used for the right as well as for the central and left connection on the radiator.

Due to the flat return flow, there is no need to chisel out the wall.

This connection can be used in conjunction with a 22 mm press fitting with “½” external thread under the HZ SLF28 skirting board (skirting board for pipes with 22 and 24 mm Ø). Please ask your composite pipe manufacturer or fitting manufacturer for the correct transition fitting.
