The V2.5X16 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 16 mm (0.63 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 21 mm (0.83 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Expect good resistance to engine and transmission fluids, aromatic hydrocarbons, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) delivers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It should not be specified for service in amines or low-molecular-weight organic acids.
It sees regular use in oil and gas, automotive fuel systems, and aerospace.
V2.5X16 ships individually. Unit weight is approximately 0.0006 g. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
