RyFlor™ Expanded PTFE Gasket

RyFlor™ ePTFE is Hi‑Tech Seals' gasket sheet material for sealing aggressive chemical, high-pressure, and high-temperature applications. It is produced from 100% virgin polytetrafluoroethylene (PTFE) that has been expanded to transform the typically rigid polymer into a soft, flexible, highly compressible sheet.

The material features a microporous network of interconnected fibres with an isotropic structure, meaning it provides equal mechanical strength in every in‑plane direction. It retains PTFE’s key properties, such as chemical inertness and thermal stability, resisting degradation in aggressive chemical and high temperature service, while reducing creep and cold flow compared to conventional PTFE sheet.

RyFlor™ has the ability to withstand assembly loads up to 40,000 psi without affecting its sealing ability. The material is also FDA‑compliant for food and beverage and pharmaceutical applications.

RyFlor™ is available in standard and custom‑cut gaskets, material strips, and joint sealant.
