568-342 PTFE ORINGS FDA

The TFE342 is an AS568-342 white PTFE (Teflon) 55 Shore D O-Ring measuring an inside diameter of 3.6 in (91.44 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.02 in (102.11 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

PTFE (Teflon) delivers non-stick, non-contaminating surface characteristics and one of the lowest coefficients of friction of any solid. The compound resists solvents, nearly all industrial chemicals, and oxidizing media. The material carries a published service range of -65°F (-53.9°C) to 500°F (260°C).

Maintenance and OEM teams specify it across semiconductor fabrication, chemical processing, and food and beverage.

Stocked as TFE342 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
