3MM CS X 34MM ID BLACK FKM 75D

APG stocks the V3X34, a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 34 mm (1.339 in), a cross section of 3 mm (0.118 in), and an outside diameter of 40 mm (1.57 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists chlorinated solvents, aggressive chemicals, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or hot water and steam call for a different compound.

It sees regular use in oil and gas, automotive fuel systems, and high-temperature process equipment.
