568-039 FKM 75 SQUARE CUT RINGS

Part number SV70039 is an AS568-039 black Viton® (FKM) 70 Shore A square profile Quad-Ring built to an inside diameter of 2.739 in (69.57 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.879 in (73.13 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) is specified here for outstanding high-temperature capability and industry benchmark where nitrile reaches its thermal limit. The compound resists engine and transmission fluids, chlorinated solvents, and many acids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or low-molecular-weight organic acids will shorten service life.

It sees regular use in oil and gas, aerospace, and automotive fuel systems.

SV70039 ships individually. Nominal inside diameter is listed as 2 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
