Aftermarket Precision-Machined Industrial Duty

Why Choose This Packing Kit

  • Designed for GM7000 displacement pumps to restore seal stack performance and check action.
  • Helps eliminate flutter, loss of prime, and bypass caused by worn packings.
  • Drop-in interface for quick bench or field rebuilds following the pump manual.

Color cue: follow orientation marks; light oil on packings during assembly improves initial seating.

Typical Compatibility

  • Graco GM7000 sprayers (examples include model numbers in the 217-614 through 217-628 series; verify your exact BOM).
  • GM7000 displacement pump assemblies shown in the Graco parts manual for that platform.
  • Also referenced by distributors as a replacement for ASM/Airlessco kit 236564 where applicable.

Always check the parts list for your exact sprayer and displacement pump assembly.
