The TFE325 is an AS568-325 white PTFE (Teflon) 55 Shore D O-Ring with an inside diameter of 1.475 in (37.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.895 in (48.13 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Expect good resistance to nearly all industrial chemicals, solvents, and oxidizing media. PTFE (Teflon) offers non-stick, non-contaminating surface characteristics and excellent dielectric properties. 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.
It sees regular use in food and beverage, aggressive-media pipelines, and semiconductor fabrication.
This item is sold individually under part number TFE325. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
