TFE329 is an AS568-329 white PTFE (Teflon) 55 Shore D O-Ring with an inside diameter of 1.975 in (50.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.395 in (60.83 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to solvents, oxidizing media, and steam. PTFE (Teflon) delivers excellent dielectric properties and one of the lowest coefficients of friction of any solid. Service temperature is rated from -65°F (-53.9°C) through 500°F (260°C).

It sees regular use in food and beverage, laboratory equipment, and chemical processing.

TFE329 ships individually. Nominal inside diameter is listed as 2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
