Part number TFE145 is an AS568-145 white PTFE (Teflon) 55 Shore D O-Ring supplied with an inside diameter of 2.55 in (64.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.756 in (70 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, PTFE (Teflon) is widely chosen for non-stick, non-contaminating surface characteristics and excellent dielectric properties. It resists nearly all industrial chemicals, oxidizing media, and steam. Rated temperature range runs from -65°F (-53.9°C) to 500°F (260°C) in continuous service.
It sees regular use in laboratory equipment, food and beverage, and aggressive-media pipelines.
Stocked as TFE145 and sold individually. Nominal inside diameter is listed as 2 9/16 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
