Ordered as SV70108, this is an AS568-108 black Viton® (FKM) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 0.237 in (6.02 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.443 in (11.25 mm). The quad-ring provides a dual sealing band on each contact face for improved reliability.
Expect good resistance to many acids, chlorinated solvents, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving ketones and esters or hot water and steam call for a different compound.
Common environments for this compound include aerospace, semiconductor equipment, and chemical processing.
This item is sold individually under part number SV70108. Application requirements vary, so validate compatibility with your process conditions prior to installation.
