Ordered as V6X125, this is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 125 mm (4.921 in), a cross section of 6 mm (0.236 in), and an outside diameter of 137 mm (5.39 in). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Expect good resistance to engine and transmission fluids, aromatic hydrocarbons, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) delivers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service.
You will find this material specified across high-temperature process equipment, semiconductor equipment, and automotive fuel systems.
This item is sold individually under part number V6X125. Unit weight is approximately 21.783 g. Review your operating media and conditions against this specification before installation. 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.
