568-474 PTFE ORINGS FDA

Part number TFE474 is an AS568-474 white PTFE (Teflon) 55 Shore D O-Ring measuring an inside diameter of 24.94 in (633.48 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 25.49 in (647.45 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

PTFE (Teflon) is specified here for very wide continuous service temperature range and one of the lowest coefficients of friction of any solid. This material stands up to nearly all industrial chemicals, oxidizing media, and solvents. Rated temperature range runs from -65°F (-53.9°C) to 500°F (260°C) in continuous service. Applications involving service requiring elastic recovery or elemental fluorine at temperature call for a different compound.

Common environments for this compound include chemical processing, aggressive-media pipelines, and laboratory equipment.

Reference part number TFE474 when ordering; the item is sold individually. Nominal inside diameter is listed as 25 inch. Review your operating media and conditions against this specification before installation.
