PSI lines pipe and fittings with 5 different types of liner. The liner choice is the most important part of the piping system because it will be in direct contact with the material conveyed. PSI plastic lined pipe and fittings meet all ASTM F1545 requirements. By using the highest quality resins we provide you with a safe and reliable product to handle your fluid management needs.
Our family of plastic liners includes PTFE, PFA, PVDF, PPL and ETFE.
