Why This Part Is Important
A piston rod is central to pump performance. As it drives the piston through each cycle, it directly affects output pressure, delivery accuracy, and overall efficiency. Replacing a worn or damaged rod with a genuine Graco 15B545 restores factory-grade movement and reduces stress on internal seals, packings, and cylinders.
Signs That the Piston Rod Needs Replacement
- Loss of pressure or inconsistent output
- Visible scoring, wear, or bending on the rod surface
- Unusual noise or vibration during operation
- Leaking due to worn packings caused by misalignment
