5MM CS X 345MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A with an inside diameter of 345 mm (13.583 in), a cross section of 5 mm (0.197 in), and an outside diameter of 355 mm (13.98 in), catalogued under part number V5X345. It remains the most cost-effective sealing element available for pressurized assemblies.

It resists aromatic hydrocarbons, many acids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is known for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

Maintenance and OEM teams specify it across automotive fuel systems, chemical processing, and oil and gas.

This item is sold individually under part number V5X345. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
