Expanded PTFE Flat Gaskets ID 89–630mm

Expanded PTFE Flat Gaskets with inside diameter sizes from 89mm to 630mm are designed for large flange connections and heavy-duty industrial sealing applications. Manufactured from expanded PTFE material, these ring gaskets provide excellent chemical resistance, long-term stability, and dependable sealing performance in demanding operating conditions.

Large-diameter ePTFE gaskets are especially suitable for applications requiring reliable sealing across wider flange surfaces. Their flexible and compressible structure helps compensate for flange imperfections, surface unevenness, and installation variations, reducing the risk of leakage in industrial systems.

Sealshub offers custom large-size expanded PTFE flat gaskets with different outside diameters (OD), inside diameters (ID), and thicknesses. Sizes from 89mm to 630mm ID are available, with customized solutions manufactured according to customer drawings, flange standards, or application requirements.

These large ePTFE ring gaskets are widely used in piping systems, chemical processing equipment, pressure vessels, reactors, heat exchangers, pumps, and industrial flange applications where corrosion resistance and reliable sealing are essential.
