568-163 PTFE ORINGS FDA

This o-ring is supplied in AS568-163 white PTFE (Teflon) 55 Shore D with an inside diameter of 5.987 in (152.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.193 in (157.3 mm), catalogued under part number TFE163. It delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to oxidizing media, steam, and solvents. That behavior comes from the compound itself: PTFE (Teflon) is widely chosen for near-universal chemical inertness and a very wide continuous service temperature range. Continuous operating temperature is published at -65°F (-53.9°C) to 500°F (260°C). Applications involving molten alkali metals or elemental fluorine at temperature call for a different compound.

You will find this material specified across laboratory equipment, semiconductor fabrication, and food and beverage.

This item is sold individually under part number TFE163. Nominal inside diameter is listed as 6 inch. Review your operating media and conditions against this specification before 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.
