APG stocks the TFE175, an AS568-175 white PTFE (Teflon) 55 Shore D O-Ring measuring an inside diameter of 8.987 in (228.27 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.193 in (233.5 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

PTFE (Teflon) is specified here for excellent dielectric properties and one of the lowest coefficients of friction of any solid. This material stands up to strong acids and bases, oxidizing media, and nearly all industrial chemicals. Continuous operating temperature is published at -65°F (-53.9°C) to 500°F (260°C).

Common environments for this compound include aggressive-media pipelines, laboratory equipment, and food and beverage.

Reference part number TFE175 when ordering; the item is sold individually. Nominal inside diameter is listed as 9 inch.
