3MM CS X 94MM ID BLACK FKM 75D

V3X94 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 94 mm (3.701 in), a cross section of 3 mm (0.118 in), and an outside diameter of 100 mm (3.94 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists aggressive chemicals, aromatic hydrocarbons, and many acids. That behavior comes from the compound itself: Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where hot water and steam or amines are present.

It sees regular use in oil and gas, chemical processing, and aerospace.
