4.5MM CS X 86MM ID BLACK FKM 75D

Part number V4.5X86 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 86 mm (3.386 in), a cross section of 4.5 mm (0.177 in), and an outside diameter of 95 mm (3.74 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against aggressive chemicals, engine and transmission fluids, 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. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where ketones and esters or amines are present.

Common environments for this compound include semiconductor equipment, aerospace, and chemical processing.

Stocked as V4.5X86 and sold individually. 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.
