-277 BLACK FKM 75D O-RING

The V75277 is an AS568-277 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 11.484 in (291.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 11.762 in (298.75 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against aggressive chemicals, engine and transmission fluids, and chlorinated solvents. Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It should not be specified for service in ketones and esters or low-molecular-weight organic acids.

Typical settings include semiconductor equipment, automotive fuel systems, and high-temperature process equipment.
