Expanded PTFE Flat Gaskets ID 6–77mm

Expanded PTFE Flat Gaskets with inside diameter sizes from 6mm to 77mm are compact sealing solutions designed for small and medium-sized flange connections, valves, pumps, instruments, and industrial equipment. Made from expanded polytetrafluoroethylene (ePTFE), these gaskets provide excellent chemical resistance, flexibility, and reliable sealing performance in demanding environments.

The soft and conformable structure of ePTFE allows these flat ring gaskets to adapt to minor surface irregularities and uneven sealing surfaces, helping achieve dependable sealing with reduced installation force. They are suitable for applications where traditional rigid PTFE gaskets may have difficulty maintaining effective contact.

Sealshub supplies custom ePTFE flat gaskets in various OD × ID × Thickness specifications, including different inside diameters from 6mm to 77mm. Standard sizes and customized dimensions are available according to drawings, sealing requirements, or equipment specifications.

With excellent resistance to acids, alkalis, solvents, moisture, and temperature variations, these small-size expanded PTFE gaskets are widely used in valves, pumps, laboratory equipment, instrumentation systems, chemical equipment, and general industrial sealing applications.
