3.5MM CS X 24MM ID BLACK FKM 75D

Ordered as V3.5X24, this is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 24 mm (0.945 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 31 mm (1.22 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists many acids, aromatic hydrocarbons, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. 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 high-temperature process equipment, aerospace, and automotive fuel systems.

Order part number V3.5X24, sold individually. Unit weight is approximately 1.5728 g. Review your operating media and conditions against this specification before installation.
