568-211 PTFE ORINGS FDA

Part number TFE211 is an AS568-211 white PTFE (Teflon) 55 Shore D O-Ring with an inside diameter of 0.796 in (20.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.074 in (27.28 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

PTFE (Teflon) is valued for non-stick, non-contaminating surface characteristics and one of the lowest coefficients of friction of any solid. The material holds up against strong acids and bases, steam, and oxidizing media. The material carries a published service range of -65°F (-53.9°C) to 500°F (260°C). Verify compatibility before use with molten alkali metals or elemental fluorine at temperature.

Common environments for this compound include semiconductor fabrication, chemical processing, and food and beverage.

Order part number TFE211, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. 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.
