568-239 FEP ENCAPSULATED VITON ORING

Part number TEV80239 is an AS568-239 black PTFE-Encapsulated Viton® 90 Shore A O-Ring measuring an inside diameter of 3.609 in (91.67 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.887 in (98.73 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists aggressive oxidizers, nearly all process chemicals, and steam. That behavior comes from the compound itself: PTFE-Encapsulated Viton® is known for excellent resistance to permeation and contamination, long service life in aggressive chemical duty. The material carries a published service range of -75°F (-59.4°C) to 400°F (204.4°C). Verify compatibility before use with installation over sharp edges without care or service requiring tight-radius dynamic flexing.

Common environments for this compound include chemical processing, semiconductor equipment, and aggressive-media valves and pumps.

Order part number TEV80239, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
