EVOH PERT Pipe 16mm x 2mm consists of 3 layers which is made up of an Evoh Oxygen Barrier (EVOH), an adhesive agent, and an inner layer of Polyethylene of Raise Temperature (PERT) .
 
The oxygen diffusion barrier encases the inner layer of PE-RT pipe completely to prevent the entry of oxygen into the heating system through the pipe. The tough outer layer is designed to withstand the demands of a worksite ensuring the oxygen barrier remains intact, reducing the risk of corrosion within the heating system.
