The 16U798 Pump Cylinder is a heavy-duty fluid-section component designed for high-pressure mortar, plaster, and fireproofing pump systems.
The Graco 16U798 Pump Cylinder serves as the primary fluid-section pump cylinder used in select Graco ToughTek material-handling and spraying systems. It houses the core pumping components including the cylinder sleeve, valves, seals, and piston interface. This component is essential for delivering consistent, high-pressure flow in heavy-duty applications such as mortar, fireproofing materials, and specialty coatings.
The 16U798 cylinder is engineered for high-pressure pumping systems that require durable, precisely machined fluid-section components. When replacing this part, ensure that your machine uses the matching pump lower layout, connection fittings, stroke length, and pressure specifications.
This pump cylinder is not universal. Installing the incorrect cylinder in a non-supported pump may cause reduced performance, leakage, or mechanical damage. Always verify machine compatibility and pump-lower model before installation.
