3MM CS X 144MM ID BLACK FKM 75D

Ordered as V3X144, this is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 144 mm (5.669 in), a cross section of 3 mm (0.118 in), and an outside diameter of 150 mm (5.91 in). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists chlorinated solvents, many acids, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

Common environments for this compound include automotive fuel systems, aerospace, and semiconductor equipment.

Reference part number V3X144 when ordering; the item is sold individually. Unit weight is approximately 5.8918 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
