Product Overview
Graco 16X456 Pump Cylinder is the OEM fluid-section cylinder used on the TexSpray Mark IV ProContractor. As the wear surface for the piston/packings, a true OEM cylinder maintains correct clearances and coating performance, helping your sprayer hold pressure, reduce pulsation, and extend packing life.
- OEM fit & finish for reliable sealing and pressure stability.
- Designed specifically for the Mark IV ProContractor (16W898) pump stack.
- Pairs correctly with matching piston rod/packing sets specified for the Mark IV.
When Should I Replace the Cylinder?
- Persistent pressure loss or spitting that new packings don’t solve.
- Visible scoring/wear inside the cylinder bore.
- Frequent premature packing failures after short runtime.

- Verify your sprayer model code and fluid pump number (e.g., 16X418) before purchase.
- Always prime with compatible fluid and follow Graco torque/spec procedures during installation.
