568-464 PTFE ORINGS FDA

The TFE464 is an AS568-464 white PTFE (Teflon) 55 Shore D O-Ring built to an inside diameter of 17.455 in (443.36 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.005 in (457.33 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

PTFE (Teflon) is specified here for near-universal chemical inertness and one of the lowest coefficients of friction of any solid. The material holds up against oxidizing media, solvents, and nearly all industrial chemicals. The material carries a published service range of -65°F (-53.9°C) to 500°F (260°C). Exposure to elemental fluorine at temperature or service requiring elastic recovery will shorten service life.

Maintenance and OEM teams specify it across food and beverage, chemical processing, and aggressive-media pipelines.

TFE464 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
