As a material, PTFE-Encapsulated Silicone is specified for 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, strong acids and solvents, and steam. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). It should not be specified for service in tight-radius dynamic flexing or installation over sharp edges.
It sees regular use in chemical processing, food and beverage processing, and cryogenic and high-temperature equipment.
TES70264 ships individually. Nominal inside diameter is listed as 7 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
