This o-ring is supplied in AS568-314 white PTFE (Teflon) 55 Shore D measuring an inside diameter of 0.725 in (18.42 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.145 in (29.08 mm), catalogued under part number TFE314. It delivers dependable bidirectional sealing in a compact groove envelope.
PTFE (Teflon) is widely chosen for a very wide continuous service temperature range and excellent dielectric properties. Expect good resistance to nearly all industrial chemicals, steam, and solvents. The material carries a published service range of -65°F (-53.9°C) to 500°F (260°C). It should not be specified for service in elemental fluorine at temperature or service requiring elastic recovery.
Maintenance and OEM teams specify it across semiconductor fabrication, chemical processing, and aggressive-media pipelines.
This item is sold individually under part number TFE314. Nominal inside diameter is listed as 3/4 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
