EPT004 Expanded PTFE stem seal

It is is a white, soft, and round PTFE gasket cord made from 100% expanded PTFE.

In possession of the characteristics of high tensile strength, improves significantly its mechanical properties,and due to the special processing method the cord seal features a higher compactness, a lower cold-flow tendency and better recovery properties. Serving as a universal spindle seal, this cord packing is ideal for harsh or pristine conditions, with a particular focus on the strict requirements of the food and pharmaceutical sectors.

Product Features

High Mechanical Strength and good Sealability

High tensile strength combined with high residual thickness at installation, ensuring reliable sealing performance under demanding, high-intensity conditions.

Excellent Self-Lubrication and Low-Friction Operation

Self-lubricating properties and a very low coefficient of sliding friction reduce wear, extend service life, and enable smooth valve operation.

Chemical Compatibility

Excellent corrosion resistance makes it suitable for a wide range of media, including acids, alkalis, solvents, fuels, and gases.

Superior Recovery and Adaptability

The good recovery properties and very good adaptability to shafts and flange surfaces ensure a long-term, reliable seal even under varying conditions.

Ultra-Clean and Food-Safe Material

A very clean material, harmless in contact with food, making it ideal for demanding hygienic applications in the food and pharmaceutical industries.
