3MM CS X 215MM ID BLACK FKM 75D

Ordered as V3X215, this is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 215 mm (8.465 in), a cross section of 3 mm (0.118 in), and an outside diameter of 221 mm (8.7 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to petroleum oils and fuels, aromatic hydrocarbons, and many acids. That behavior comes from the compound itself: Viton® (FKM) is valued for very low compression set at elevated temperature and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

Common environments for this compound include aerospace, high-temperature process equipment, and chemical processing.

Stocked as V3X215 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
