3MM CS X 155MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A built to an inside diameter of 155 mm (6.102 in), a cross section of 3 mm (0.118 in), and an outside diameter of 161 mm (6.34 in), catalogued under part number V3X155. It compresses into its gland to block fluid or gas migration across a joint.

It resists chlorinated solvents, many acids, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, 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).

It sees regular use in aerospace, automotive fuel systems, and oil and gas.

This item is sold individually under part number V3X155. Unit weight is approximately 6.535 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
