This o-ring is supplied in AS568-241 black PTFE-Encapsulated Viton® 90 Shore A supplied with an inside diameter of 3.859 in (98.02 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.137 in (105.08 mm), catalogued under part number TEV80241. It creates a positive seal at flange, piston and rod interfaces without added hardware.
PTFE-Encapsulated Viton® delivers long service life in aggressive chemical duty and a non-stick sealing surface that resists fouling. The compound resists nearly all process chemicals, strong acids and solvents, and steam. Continuous operating temperature is published at -75°F (-59.4°C) to 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 chemical processing, semiconductor equipment, and aggressive-media valves and pumps.
This item is sold individually under part number TEV80241. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
