568-276 PTFE ORINGS FDA

The TFE276 is an AS568-276 white PTFE (Teflon) 55 Shore D O-Ring built to an inside diameter of 10.984 in (278.99 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 11.262 in (286.05 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, PTFE (Teflon) delivers excellent dielectric properties and a very wide continuous service temperature range. Expect good resistance to oxidizing media, solvents, and nearly all industrial chemicals. Continuous operating temperature is published at -65°F (-53.9°C) to 500°F (260°C).

Maintenance and OEM teams specify it across pharmaceutical and biotech, laboratory equipment, and chemical processing.

TFE276 ships individually. Nominal inside diameter is listed as 11 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
