TFE275 is an AS568-275 white PTFE (Teflon) 55 Shore D O-Ring measuring an inside diameter of 10.484 in (266.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.762 in (273.35 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
This material stands up to oxidizing media, steam, and solvents. PTFE (Teflon) is known for one of the lowest coefficients of friction of any solid and a very wide continuous service temperature range. Continuous operating temperature is published at -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.
It sees regular use in aggressive-media pipelines, chemical processing, and food and beverage.
Stocked as TFE275 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
