3.5MM CS X 54MM ID BLACK FKM 75D

Part number V3.5X54 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 54 mm (2.126 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 61 mm (2.4 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to engine and transmission fluids, aromatic hydrocarbons, and many acids. That behavior comes from the compound itself: Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C).

It sees regular use in chemical processing, semiconductor equipment, and aerospace.

Stocked as V3.5X54 and sold individually. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
