WAVIN Hep2O Barrier Pipe - Coiled Lengths

Hep2 is a flexible, push-fit plumbing system that has been developed for professional installers and is suitable for domestic hot and cold water supply, including potable water, as well as central and underfloor heating.

Hep2 comprises flexible straight-coiled polybutylene pipework and fittings that incorporate an integral push-fit mechanism. Greater pipe flexibility, long coil lengths and guaranteed joint performance enable installations to be completed with fewer joints, minimising system costs.

Hep2 is available in either a Standard or Barrier Pipe format: Hep2Standard Pipe is made from polybutylene; Hep2O® Barrier Pipe has a layer of ethylene vinyl alcohol that prevents oxygen diffusion through the pipe wall when used for central and underfloor heating systems.
