568-415 PTFE ORINGS FDA

Ordered as TFE415, this is an AS568-415 white PTFE (Teflon) 55 Shore D O-Ring with an inside diameter of 3.225 in (81.92 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.775 in (95.89 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

PTFE (Teflon) is valued for a very wide continuous service temperature range and non-stick, non-contaminating surface characteristics. Expect good resistance to nearly all industrial chemicals, strong acids and bases, and solvents. Published continuous service range is -65°F (-53.9°C) to 500°F (260°C). Applications involving elemental fluorine at temperature or molten alkali metals call for a different compound.

Maintenance and OEM teams specify it across chemical processing, semiconductor fabrication, and aggressive-media pipelines.

Reference part number TFE415 when ordering; the item is sold individually. Nominal inside diameter is listed as 3 1/4 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.
