PTFE-Encapsulated Silicone is specified here for strong resistance to permeation and non-contaminating, non-stick sealing surface. This material stands up to nearly all process chemicals, wide temperature swings, and steam. Published continuous service range is -75°F (-59.4°C) to 400°F (204.4°C). Applications involving tight-radius dynamic flexing or installation over sharp edges call for a different compound.

It sees regular use in food and beverage processing, pharmaceutical manufacturing, and cryogenic and high-temperature equipment.

Stocked as TES70434 and sold individually. Nominal inside diameter is listed as 5 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
