Ordered as V3X12, this is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 12 mm (0.472 in), a cross section of 3 mm (0.118 in), and an outside diameter of 18 mm (0.71 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. Viton® (FKM) is specified for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to ketones and esters or amines will shorten service life.
Common environments for this compound include automotive fuel systems, oil and gas, and semiconductor equipment.
Reference part number V3X12 when ordering; the item is sold individually. Unit weight is approximately 0.6169 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
