Ordered as TFE160, this is an AS568-160 white PTFE (Teflon) 55 Shore D O-Ring with an inside diameter of 5.237 in (133.02 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.443 in (138.25 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.
PTFE (Teflon) is known for a very wide continuous service temperature range and near-universal chemical inertness. The material holds up against solvents, oxidizing media, and nearly all industrial chemicals. Rated temperature range runs from -65°F (-53.9°C) to 500°F (260°C) in continuous service. Exposure to service requiring elastic recovery or molten alkali metals will shorten service life.
It sees regular use in laboratory equipment, aggressive-media pipelines, and semiconductor fabrication.
Reference part number TFE160 when ordering; the item is sold individually. Nominal inside diameter is listed as 5 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
