An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Supplementary detail from the product record: ORING 70 Durometer.
PTFE-Encapsulated Silicone is specified here for chemical inertness of PTFE with the wide temperature range of silicone and seamless PTFE jacket over a resilient silicone core. The compound resists wide temperature swings, strong acids and solvents, and nearly all process chemicals. Published continuous service range is -75°F (-59.4°C) to 400°F (204.4°C). It should not be specified for service in installation over sharp edges or tight-radius dynamic flexing.
Typical settings include pharmaceutical manufacturing, food and beverage processing, and cryogenic and high-temperature equipment.
This item is sold individually under part number TES70241. Check the compound against your process media, pressure and temperature before committing to a design.
