568-224 PTFE ORINGS FDA

The TFE224 is an AS568-224 white PTFE (Teflon) 55 Shore D O-Ring supplied with an inside diameter of 1.734 in (44.04 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.012 in (51.1 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists strong acids and bases, nearly all industrial chemicals, and steam. PTFE (Teflon) is specified for non-stick, non-contaminating surface characteristics and near-universal chemical inertness. Rated temperature range runs from -65°F (-53.9°C) to 500°F (260°C) in continuous service. It should not be specified for service in service requiring elastic recovery or molten alkali metals.

Maintenance and OEM teams specify it across semiconductor fabrication, chemical processing, and pharmaceutical and biotech.

Stocked as TFE224 and sold individually. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
