Part number V2.5X15.5 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 15.5 mm (0.61 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 20.5 mm (0.81 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Expect good resistance to engine and transmission fluids, aggressive chemicals, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit 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).
It sees regular use in high-temperature process equipment, oil and gas, and aerospace.
Order part number V2.5X15.5, sold individually. Unit weight is approximately 0.512 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
