568-347 PTFE ORINGS FDA

This o-ring is supplied in AS568-347 white PTFE (Teflon) 55 Shore D measuring an inside diameter of 4.225 in (107.32 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.645 in (117.98 mm), catalogued under part number TFE347. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, PTFE (Teflon) is widely chosen for near-universal chemical inertness and one of the lowest coefficients of friction of any solid. It resists solvents, oxidizing media, and steam. Rated temperature range runs from -65°F (-53.9°C) to 500°F (260°C) in continuous service. It should not be specified for service in service requiring elastic recovery or molten alkali metals.

You will find this material specified across semiconductor fabrication, chemical processing, and laboratory equipment.

This item is sold individually under part number TFE347. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
