568-369 PTFE ORINGS FDA

The TFE369 is an AS568-369 white PTFE (Teflon) 55 Shore D O-Ring measuring an inside diameter of 7.975 in (202.57 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 8.395 in (213.23 mm). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

PTFE (Teflon) is specified here for excellent dielectric properties and near-universal chemical inertness. This material stands up to strong acids and bases, nearly all industrial chemicals, and steam. The material carries a published service range of -65°F (-53.9°C) to 500°F (260°C). Exposure to service requiring elastic recovery or molten alkali metals will shorten service life.

Maintenance and OEM teams specify it across pharmaceutical and biotech, aggressive-media pipelines, and chemical processing.

Reference part number TFE369 when ordering; the item is sold individually. Nominal inside diameter is listed as 8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
