5.33MM CS X 139.7MM ID BLACK FKM 75D

The V5.33X139.7 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 139.7 mm (5.5 in), a cross section of 5.33 mm (0.21 in), and an outside diameter of 150.36 mm (5.92 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to petroleum oils and fuels, many acids, and chlorinated solvents. Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with hot water and steam or low-molecular-weight organic acids.

Maintenance and OEM teams specify it across semiconductor equipment, chemical processing, and aerospace.
