Ordered as TEV80441, this is an AS568-441 black PTFE-Encapsulated Viton® 90 Shore A O-Ring measuring an inside diameter of 6.975 in (177.17 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 7.525 in (191.14 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.
As a material, PTFE-Encapsulated Viton® delivers chemical inertness of PTFE with the memory of a rubber o-ring and long service life in aggressive chemical duty. The compound resists aggressive oxidizers, strong acids and solvents, and steam. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). Applications involving installation over sharp edges without care or service requiring tight-radius dynamic flexing call for a different compound.
You will find this material specified across food and beverage, semiconductor equipment, and aggressive-media valves and pumps.
Reference part number TEV80441 when ordering; the item is sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
