PTFE-Encapsulated Silicone offers a non-contaminating, non-stick sealing surface and chemical inertness of PTFE with the wide temperature range of silicone. The compound resists nearly all process chemicals, wide temperature swings, and steam. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). It is not the right choice where installation over sharp edges or tight-radius dynamic flexing are present.
Typical settings include food and beverage processing, chemical processing, and cryogenic and high-temperature equipment.
TES70377 ships individually. Nominal inside diameter is listed as 10 inch. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
