4MM CS X 73MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A built to an inside diameter of 73 mm (2.874 in), a cross section of 4 mm (0.157 in), and an outside diameter of 81 mm (3.19 in), catalogued under part number V4X73. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Viton® (FKM) is specified for very low compression set at elevated temperature and outstanding high-temperature capability. The material holds up against chlorinated solvents, aromatic hydrocarbons, and engine and transmission fluids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving low-molecular-weight organic acids or hot water and steam call for a different compound.

You will find this material specified across semiconductor equipment, high-temperature process equipment, and aerospace.

This item is sold individually under part number V4X73. Unit weight is approximately 5.4911 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
