3.1MM CS X 144.4MM ID BLACK FKM 75D

The V3.1X144.4 is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 144.4 mm (5.685 in), a cross section of 3.1 mm (0.122 in), and an outside diameter of 150.6 mm (5.93 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. The catalog record notes: Metric O-RING, JIS G145.

Expect good resistance to aromatic hydrocarbons, many acids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) delivers long service life in hot, chemically aggressive environments and outstanding high-temperature capability. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or amines call for a different compound.

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

V3.1X144.4 ships individually. Unit weight is approximately 6.4704 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
