The GRACO 16U420 is a rod coupler designed for use within GRACO pump assemblies. It is a mechanical component that connects the rod to the pump mechanism, ensuring proper force transmission and alignment. The material is not explicitly specified in available documentation, but typical GRACO couplers are constructed from durable metals such as steel or alloy for strength and longevity. Its intended use is to facilitate reliable operation and maintenance of GRACO hydraulic and displacement pump systems. Key Features: Coupler, Rod, Pump 16U420 Compatible with GRACO pump assemblies, including models referenced in GRACO GH Series Big Rig Sprayers and RoadLazer HPS hydraulic pumping systems Designed for secure rod-to-pump connection Facilitates force transmission and alignment Supports reliable pump operation and maintenance Applications:Used in GRACO hydraulic and displacement pump systems for applications such as road marking, industrial spraying, and fluid transfer in various industries including mining, agriculture, and construction. Installation Notes: Using genuine GRACO parts like the 16U420 ensures optimal performance, safety, and longevity of the equipment. Non-genuine parts may compromise system integrity and void warranties. Ensure the pump is depressurized and isolated from power sources before installation Follow GRACO equipment manual instructions for disassembly and reassembly Inspect the coupler and mating surfaces for wear or damage before installation Use appropriate tools to avoid damaging the coupler or rod Regularly check the coupler for signs of wear or misalignment during routine maintenance
