568-280 PTFE ORINGS FDA

Part number TFE280 is an AS568-280 white PTFE (Teflon) 55 Shore D O-Ring with an inside diameter of 13.984 in (355.19 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 14.262 in (362.25 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to oxidizing media, nearly all industrial chemicals, and strong acids and bases. That behavior comes from the compound itself: PTFE (Teflon) offers one of the lowest coefficients of friction of any solid and near-universal chemical inertness. The material carries a published service range of -65°F (-53.9°C) to 500°F (260°C).

Common environments for this compound include semiconductor fabrication, aggressive-media pipelines, and laboratory equipment.

This item is sold individually under part number TFE280. Nominal inside diameter is listed as 14 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.
