Ordered as SV70008, this is an AS568-008 black Viton® (FKM) 70 Shore A Square-Cut Ring with an inside diameter of 0.176 in (4.47 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.316 in (8.03 mm). The square-cut ring presents a flat rectangular section that cannot roll or twist in its groove, making it a dependable static seal.
Viton® (FKM) delivers outstanding high-temperature capability and very low compression set at elevated temperature. The material holds up against many acids, aggressive chemicals, and aromatic hydrocarbons. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or amines will shorten service life. The profile itself contributes a rectangular section that will not roll in the groove and a flat contact band that spreads sealing load across a wider area. 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 aerospace, high-temperature process equipment, and automotive fuel systems.
SV70008 ships individually. Unit weight is approximately 0.093 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
