The 421244-L hydraulic accessory belongs to the Vickers Hydraulic Accessories series and is produced by Vickers. As an auxiliary component for hydraulic automation, it mates to 25VQ pump frames to guide fluid flow and maintain correct orientation in assembled packs. It measures 3.55 in in length, 3.81 in in width, and 3.81 in in height, allowing straightforward integration inside standard power units. The assembly weighs 8 lb, so routine handling can be performed without lifting equipment. Clockwise, right-hand rotation is supported, matching the shaft direction on compatible Vickers pumps.
The accessory carries a maximum working pressure rating of 172 bar (2500 psi) that keeps the housing within safe limits during continuous duty. A nominal flow capacity of 12 gpm matches the displacement of many mid-size systems. Sealing is handled by a Buna-N O-ring, which provides resilience against common hydraulic oils. The O-ring cross-section is 0.139 in, its inside diameter is 3.859 in, and its outside diameter is 3.998 in, dimensions that establish the correct compression in the groove. These parameters promote leak-free operation and stable performance throughout automated hydraulic equipment.
