APG stocks the TFE336, an AS568-336 white PTFE (Teflon) 55 Shore D O-Ring supplied with an inside diameter of 2.85 in (72.39 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.27 in (83.06 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Expect good resistance to steam, nearly all industrial chemicals, and solvents. That behavior comes from the compound itself: PTFE (Teflon) is specified for a very wide continuous service temperature range and excellent dielectric properties. Service temperature is rated from -65°F (-53.9°C) through 500°F (260°C). Verify compatibility before use with elemental fluorine at temperature or service requiring elastic recovery.
Maintenance and OEM teams specify it across aggressive-media pipelines, laboratory equipment, and pharmaceutical and biotech.
This item is sold individually under part number TFE336. Nominal inside diameter is listed as 2 7/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need?
