3MM CS X 30.5MM ID BLACK FKM 75D

The V3X30.5 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 30.5 mm (1.201 in), a cross section of 3 mm (0.118 in), and an outside diameter of 36.5 mm (1.44 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to many acids, petroleum oils and fuels, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is valued for outstanding high-temperature capability and very low compression set at elevated temperature. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines or low-molecular-weight organic acids.

Common environments for this compound include high-temperature process equipment, semiconductor equipment, and oil and gas.

Stocked as V3X30.5 and sold individually. Unit weight is approximately 1.35 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
