he HENCO 3L PE-RT pipes are made of three layers. They feature a PE-RT inner pipe, an adhesive layer and an EVOH oxygen barrier. Thanks to the oxygen barrier the pipe responds to the requirements specified in DIN 4726 for oxygen diffusion in heating systems. Thus the HENCO 3L PE-RT pipes are perfectly suitable for use in heating installations.
