An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The material holds up against aggressive oxidizers, steam, and strong acids and solvents. PTFE-Encapsulated Viton® is known for a seamless PTFE jacket over a resilient elastomer core and chemical inertness of PTFE with the memory of a rubber o-ring. Continuous operating temperature is published at -75°F (-59.4°C) to 400°F (204.4°C). It should not be specified for service in service requiring tight-radius dynamic flexing or installation over sharp edges without care.
Typical settings include chemical processing, semiconductor equipment, and food and beverage.
Reference part number TEV80140 when ordering; the item is sold individually. Nominal inside diameter is listed as 2 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
