3.5MM CS X 87MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A supplied with an inside diameter of 87 mm (3.425 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 94 mm (3.7 in), catalogued under part number V3.5X87. It remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to aromatic hydrocarbons, petroleum oils and fuels, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is known for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.

You will find this material specified across aerospace, chemical processing, and semiconductor equipment.

This item is sold individually under part number V3.5X87. Unit weight is approximately 5.032 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
