4MM CS X 69MM ID BLACK FKM 75D

Ordered as V4X69, this is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 69 mm (2.717 in), a cross section of 4 mm (0.157 in), and an outside diameter of 77 mm (3.03 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

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

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