This o-ring is supplied in AS568-261 black PTFE-Encapsulated Viton® 90 Shore A measuring an inside diameter of 6.734 in (171.04 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 7.012 in (178.1 mm), catalogued under part number TEV80261. It remains the most cost-effective sealing element available for pressurized assemblies.
This material stands up to nearly all process chemicals, aggressive oxidizers, and steam. PTFE-Encapsulated Viton® is valued for excellent resistance to permeation and contamination, long service life in aggressive chemical duty. Continuous operating temperature is published at -75°F (-59.4°C) to 400°F (204.4°C). Exposure to installation over sharp edges without care or service requiring tight-radius dynamic flexing will shorten service life.
Maintenance and OEM teams specify it across aggressive-media valves and pumps, pharmaceutical manufacturing, and semiconductor equipment.
This item is sold individually under part number TEV80261. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
