An ANSI Flex® Gasket's contact surface is PTFE that is unitized to an EPDM rubber inner core. This totally bonded construction provides a PTFE Gasket with the mechanical characteristics, including memory, of an elastomer gasket with exceptional steam resistance. An ANSI-Flex® Gasket is ideal for applications, such as PVC piping and glass lining piping, where low seating stress is required.
