Cylinder head and cap are precision components that seal hydraulic ram cylinders, containing pressure and guiding piston movement.
The cylinder head and cap form the end closures of a hydraulic ram cylinder assembly. The head typically contains port connections for hydraulic fluid entry/exit and mounting features, while the cap provides the opposite end seal. Together they create a pressure-tight chamber that contains the piston and hydraulic fluid, withstanding high pressures while maintaining precise alignment for smooth piston operation. They incorporate sealing surfaces, bearing areas for piston rod support, and often include integrated valve or sensor mounting provisions.

The cylinder head typically contains hydraulic ports and mounting features, while the cap provides the opposite end closure. Both serve as pressure-containing ends but may have different functional requirements.
They undergo hydrostatic pressure testing at 1.5x working pressure, followed by dimensional inspection and leak testing with helium or pressure decay methods.
Minor surface damage can be repaired by machining and re-plating, but structural cracks or severe corrosion typically require replacement due to safety concerns.
