-248 BLACK FKM 90D O-RING

Part number V90248 is an AS568-248 black Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 4.734 in (120.24 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.012 in (127.3 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Viton® (FKM) delivers outstanding high-temperature capability, excellent resistance to compression set and permeation. Expect good resistance to petroleum oils and fuels, chlorinated solvents, and many acids. Service temperature is rated from -15°F (-26.1°C) through 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 chemical processing, automotive fuel systems, and aerospace.

V90248 ships individually. Unit weight is approximately 6.8951 g and nominal inside diameter is listed as 4 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
