3.5MM CS X 103MM ID BLACK FKM 75D

The V3.5X103 is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 103 mm (4.055 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 110 mm (4.33 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists chlorinated solvents, aromatic hydrocarbons, and many acids. Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service.

Maintenance and OEM teams specify it across high-temperature process equipment, automotive fuel systems, and chemical processing.
