It provides a reliable static or dynamic seal by deforming into its gland under assembly load. This item is further identified as ORING 70 Durometer.
PTFE-Encapsulated Silicone is specified here for excellent recovery across extreme temperature cycling and seamless PTFE jacket over a resilient silicone core. This material stands up to strong acids and solvents, nearly all process chemicals, and steam. Rated temperature range runs from -75°F (-59.4°C) to 400°F (204.4°C) in continuous service. Exposure to installation over sharp edges or tight-radius dynamic flexing will shorten service life.
You will find this material specified across food and beverage processing, pharmaceutical manufacturing, and chemical processing.
Order part number TES70029, sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
