The 02-102539 hydraulic accessory belongs to the Vickers Hydraulic Accessories series and is manufactured by Vickers. It supports hydraulic automation by forming the sealed interface between the pump casing and adjacent pipework. The accessory fits pump model 25V-A21-122R, allowing direct installation without adapters. Its frame size is specified as 25V. Overall length is 3.89 in, while height and width are each 4.14 in, producing a compact square profile that eases orientation inside tight manifolds. With a weight of 8.00 lb, it remains light enough for manual handling during routine maintenance.
An O-ring numbered 154095 is included to achieve a static seal at the mating surface. The ring carries an inside diameter of 3.859 in and an outside diameter of 3.998 in so it seats properly against the machined groove. Its thickness of 0.139 in provides the compression needed for leak-free operation. The accessory is rated for a ring capacity of 21 GPM, ensuring that pumps operating at that flow do not experience undue pressure drop through the sealed joint. These values together secure reliable performance when the unit is mounted on the designated frame and pump model.
