This o-ring is supplied in black Viton® (FKM) 75 Shore A supplied with an inside diameter of 18 mm (0.709 in), a cross section of 3 mm (0.118 in), and an outside diameter of 24 mm (0.94 in), catalogued under part number V3X18. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
This material stands up to engine and transmission fluids, aggressive chemicals, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with amines or ketones and esters.
Typical settings include high-temperature process equipment, oil and gas, and aerospace.
Reference part number V3X18 when ordering; the item is sold individually. Unit weight is approximately 0.851 g. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
