PTFE lip gaskets are specialized sealing solutions designed for tight spaces and high-performance environments. Their unique thin cross-section and thick lip enable effective sealing under compression, making them ideal for applications requiring chemical resistance, extreme temperature tolerance, and electrical insulation. These gaskets find widespread use across industries like chemical processing, automotive, aerospace, and medical sectors, where their non-corrosive, non-stick properties and durability are critical. From valve stem seals to aircraft hydraulic systems, PTFE lip gaskets provide reliable performance in demanding conditions while maintaining flexibility in constrained spaces.
