Wavin HXX25/28W Hep2O 28mm Barrier Pipe 25 m Coil

The Wavin HXX25/28W is a 25 metre coil of Hep2O barrier pipe in 28 mm outside diameter, made from polybutylene (PB). It is designed for central heating systems and can also be used for domestic hot and cold water services. The pipe incorporates an oxygen barrier to inhibit oxygen permeation.

It suits professional plumbers and heating engineers working on domestic and other buildings with Hep2O push-fit fittings. The pipe is supplied in an orange-coded colour scheme that identifies the 28 mm size.
