The SV70332 is an AS568-332 black Viton® (FKM) 70 Shore A Square-Cut Ring supplied with an inside diameter of 2.35 in (59.69 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.77 in (70.36 mm). This square-cut ring offers greater contact area against the gland wall than an equivalent o-ring.
Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. This material stands up to petroleum oils and fuels, aromatic hydrocarbons, and aggressive chemicals. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where ketones and esters or amines are present. The profile itself contributes a flat contact band that spreads sealing load across a wider area and a rectangular section that will not roll in the groove. Note that a square section is less suited to high-speed rotary service, where the larger contact area raises friction and heat.
Common environments for this compound include semiconductor equipment, automotive fuel systems, and aerospace.
