Caterpillar 090-9620 Tube Assembly Hydraulic Cylinder

Caterpillar 090-9620 Tube Assembly Hydraulic Cylinder is the tube portion of a Caterpillar hydraulic cylinder, listed under part numbers 090-9620, 909620, and 0909620. This tube assembly forms the cylindrical housing that guides the piston and provides the bore within CAT hydraulic systems, enabling the translation of hydraulic pressure into linear motion. It’s used in Caterpillar equipment wherever a replacement or component tube of the cylinder assembly is required, and it aligns with CAT replacement part practices by catalog number. Buyers can cross-reference their cylinder models against the CAT part numbers to ensure compatibility with Caterpillar hydraulic cylinder assemblies. In maintenance or repair settings, this tube assembly serves as the core cylindrical body of the cylinder, critical to sealing, alignment, and smooth actuation when installed as part of a full cylinder assembly.
