568-124 PTFE ORINGS FDA

The TFE124 is an AS568-124 white PTFE (Teflon) 55 Shore D O-Ring measuring an inside diameter of 1.237 in (31.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.443 in (36.65 mm). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

PTFE (Teflon) is specified here for non-stick, non-contaminating surface characteristics and near-universal chemical inertness. It resists strong acids and bases, oxidizing media, and solvents. Rated temperature range runs from -65°F (-53.9°C) to 500°F (260°C) in continuous service. Exposure to molten alkali metals or service requiring elastic recovery will shorten service life.

Maintenance and OEM teams specify it across pharmaceutical and biotech, semiconductor fabrication, and laboratory equipment.

Reference part number TFE124 when ordering; the item is sold individually. Nominal inside diameter is listed as 1 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
