This quad-ring is supplied in AS568-028 black Viton® (FKM) 70 Shore A square profile supplied with an inside diameter of 1.364 in (34.65 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.504 in (38.2 mm), catalogued under part number SV70028. It uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

The material holds up against petroleum oils and fuels, many acids, and aggressive chemicals. Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving amines or ketones and esters call for a different compound.

Typical settings include high-temperature process equipment, automotive fuel systems, and semiconductor equipment.
