568-271 PTFE ORINGS FDA

Ordered as TFE271, this is an AS568-271 white PTFE (Teflon) 55 Shore D O-Ring supplied with an inside diameter of 9.234 in (234.54 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.512 in (241.6 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against nearly all industrial chemicals, oxidizing media, and steam. That behavior comes from the compound itself: PTFE (Teflon) delivers excellent dielectric properties and one of the lowest coefficients of friction of any solid. Published continuous service range is -65°F (-53.9°C) to 500°F (260°C).

It sees regular use in chemical processing, pharmaceutical and biotech, and food and beverage.

TFE271 ships individually. Nominal inside diameter is listed as 9 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
