568-335 PTFE ORINGS FDA

TFE335 is an AS568-335 white PTFE (Teflon) 55 Shore D O-Ring measuring an inside diameter of 2.725 in (69.22 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.145 in (79.88 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

PTFE (Teflon) is specified here for one of the lowest coefficients of friction of any solid and near-universal chemical inertness. It resists oxidizing media, solvents, and strong acids and bases. Rated temperature range runs from -65°F (-53.9°C) to 500°F (260°C) in continuous service.

Typical settings include chemical processing, semiconductor fabrication, and aggressive-media pipelines.
