568-463 PTFE ORINGS FDA

Part number TFE463 is an AS568-463 white PTFE (Teflon) 55 Shore D O-Ring built to an inside diameter of 16.955 in (430.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 17.505 in (444.63 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

PTFE (Teflon) is widely chosen for one of the lowest coefficients of friction of any solid and a very wide continuous service temperature range. Expect good resistance to steam, strong acids and bases, and nearly all industrial chemicals. The material carries a published service range of -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.

Typical settings include food and beverage, aggressive-media pipelines, and semiconductor fabrication.

Reference part number TFE463 when ordering; the item is sold individually. Nominal inside diameter is listed as 17 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
