568-266 FKM 75 SQUARE CUT RINGS

This quad-ring is supplied in AS568-266 black Viton® (FKM) 70 Shore A square profile with an inside diameter of 7.984 in (202.79 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.262 in (209.85 mm), catalogued under part number SV70266. It resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

The compound resists many acids, aggressive chemicals, and engine and transmission fluids. Viton® (FKM) delivers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or amines will shorten service life.

Typical settings include oil and gas, chemical processing, and automotive fuel systems.

This item is sold individually under part number SV70266. As always, verify media compatibility and operating conditions against the requirements of your specific application.
