TFE142 is an AS568-142 white PTFE (Teflon) 55 Shore D O-Ring supplied with an inside diameter of 2.362 in (59.99 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.568 in (65.23 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The material holds up against strong acids and bases, solvents, and steam. That behavior comes from the compound itself: PTFE (Teflon) is known for one of the lowest coefficients of friction of any solid and a very wide continuous service temperature range. Continuous operating temperature is published at -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.
Typical settings include aggressive-media pipelines, food and beverage, and chemical processing.
Stocked as TFE142 and sold individually. Nominal inside diameter is listed as 2 3/8 inch. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
