A PTFE-lined cross is a four-way pipe fitting used to join pipelines in right angle directions to provide fluid flow in directions other than one. With a lining of Polytetrafluoroethylene (PTFE), it has excellent resistance to heat, corrosion, and chemical reaction. This fit is perfect for rigorous process conditions where reliability and purity are imperative. Commonly employed in the petrochemical, pharmaceutical and chemical industries, the PTFE-lined cross provides a leak-proof, smooth flow at four-way intersections to allow efficient distribution and accurate control within intricate piping systems.
