3.5MM CS X 125MM ID BLACK FKM 75D

Part number V3.5X125 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 125 mm (4.921 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 132 mm (5.2 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) is valued for very low compression set at elevated temperature, excellent resistance to compression set and permeation. Expect good resistance to aggressive chemicals, aromatic hydrocarbons, and many acids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or hot water and steam will shorten service life.

You will find this material specified across high-temperature process equipment, chemical processing, and automotive fuel systems.

This item is sold individually under part number V3.5X125. Check the compound against your process media, pressure and temperature before committing to a design.
