568-202 PTFE ORINGS FDA

TFE202 is an AS568-202 white PTFE (Teflon) 55 Shore D O-Ring built to an inside diameter of 0.234 in (5.94 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.512 in (13 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

PTFE (Teflon) is specified here for excellent dielectric properties and one of the lowest coefficients of friction of any solid. The material holds up against nearly all industrial chemicals, strong acids and bases, and solvents. Service temperature is rated from -65°F (-53.9°C) through 500°F (260°C). Applications involving molten alkali metals or elemental fluorine at temperature call for a different compound.

Maintenance and OEM teams specify it across laboratory equipment, pharmaceutical and biotech, and aggressive-media pipelines.

This item is sold individually under part number TFE202. Nominal inside diameter is listed as 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
