This square-cut ring is supplied in AS568-036 black Viton® (FKM) 70 Shore A measuring an inside diameter of 2.364 in (60.05 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.504 in (63.6 mm), catalogued under part number SV70036. It presents a flat rectangular section that cannot roll or twist in its groove, making it a dependable static seal.
Viton® (FKM) is known for outstanding high-temperature capability, excellent resistance to compression set and permeation. This material stands up to petroleum oils and fuels, engine and transmission fluids, and many acids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life. The profile itself contributes a rectangular section that will not roll in the groove and greater resistance to extrusion than a round section of the same size. Note that a square section is less suited to high-speed rotary service, where the larger contact area raises friction and heat.
Typical settings include automotive fuel systems, high-temperature process equipment, and aerospace.
Reference part number SV70036 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
