568-386 PTFE ORINGS FDA

TFE386 is an AS568-386 white PTFE (Teflon) 55 Shore D O-Ring with an inside diameter of 16.955 in (430.66 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 17.375 in (441.33 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to steam, solvents, and oxidizing media. PTFE (Teflon) is known for one of the lowest coefficients of friction of any solid and excellent dielectric properties. Continuous operating temperature is published at -65°F (-53.9°C) to 500°F (260°C). It should not be specified for service in elemental fluorine at temperature or molten alkali metals.

Maintenance and OEM teams specify it across aggressive-media pipelines, semiconductor fabrication, and food and beverage.

TFE386 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
