568-129 PTFE ORINGS FDA

TFE129 is an AS568-129 white PTFE (Teflon) 55 Shore D O-Ring supplied with an inside diameter of 1.549 in (39.34 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.755 in (44.58 mm). In service, this 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 valued for non-stick, non-contaminating surface characteristics and near-universal chemical inertness. This material stands up to steam, strong acids and bases, and oxidizing media. Published continuous service range is -65°F (-53.9°C) to 500°F (260°C). Applications involving service requiring elastic recovery or elemental fluorine at temperature call for a different compound.

You will find this material specified across food and beverage, semiconductor fabrication, and laboratory equipment.

TFE129 ships individually. Nominal inside diameter is listed as 1 9/16 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
