Wavin HD1/22W Hep2O 22mm Push-Fit Straight Coupler

The Wavin HD1/22W is a 22mm straight push-fit coupler for the Hep2O system, connecting two 22mm Hep2O pipe ends in a straight run. Both connections are push-fit inserts, so no tools or naked flames are needed to make the joint.

It suits plumbers and heating engineers working on domestic water distribution and central heating systems, including pressurised systems and combination boilers. It is a replacement or new-install fitting for Hep2O pipework.

The fitting is a one-part white design with an untreated connection finish. Hep2O is supplied with Key or Keyless demounting options, so the coupler works with either system’s pipe and fittings.
