5MM CS X 260MM ID BLACK FKM 75D

Part number V5X260 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 260 mm (10.236 in), a cross section of 5 mm (0.197 in), and an outside diameter of 270 mm (10.63 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Viton® (FKM) is specified for excellent resistance to compression set and permeation, outstanding high-temperature capability. Expect good resistance to engine and transmission fluids, petroleum oils and fuels, and many acids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or ketones and esters will shorten service life.

Maintenance and OEM teams specify it across aerospace, automotive fuel systems, and high-temperature process equipment.

V5X260 ships individually. Unit weight is approximately 29.997 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
