7MM CS X 475MM ID BLACK FKM 70D

Part number V7X475 is a black Viton® (FKM) 70 Shore A O-Ring built to an inside diameter of 475 mm (18.701 in), a cross section of 7 mm (0.276 in), and an outside diameter of 489 mm (19.25 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against petroleum oils and fuels, many acids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or ketones and esters call for a different compound.

Typical settings include aerospace, high-temperature process equipment, and semiconductor equipment.

V7X475 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
