5.7MM CS X 59.6MM ID BLACK FKM 75D

Ordered as V5.7X59.6, this is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 59.6 mm (2.346 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 71 mm (2.8 in). The o-ring compresses into its gland to block fluid or gas migration across a joint. Source specification: Metric O-RING, JIS P60.

The material holds up against engine and transmission fluids, petroleum oils and fuels, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

It sees regular use in semiconductor equipment, aerospace, and oil and gas.
