568-334 PTFE ORINGS FDA

Part number TFE334 is an AS568-334 white PTFE (Teflon) 55 Shore D O-Ring built to an inside diameter of 2.6 in (66.04 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.02 in (76.71 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to solvents, nearly all industrial chemicals, and steam. PTFE (Teflon) is widely chosen for excellent dielectric properties and one of the lowest coefficients of friction of any solid. The material carries a published service range of -65°F (-53.9°C) to 500°F (260°C). Applications involving molten alkali metals or elemental fluorine at temperature call for a different compound.

Common environments for this compound include chemical processing, food and beverage, and semiconductor fabrication.

Reference part number TFE334 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
