Frequently Asked Questions

It fits the listed GH models, but Graco has serial-number breaks and pump revisions. Always cross-check your exact model/serial in the official parts list before ordering.

Strongly recommended. A fresh packing/seal kit ensures proper sealing against the new cylinder bore and maximizes service life.

Scoring visible in the bore, repeated packing failures, pressure drop, pulsation, or material bypass are common signs the cylinder needs replacement.

No. This is the cylinder (fluid housing) only. Other components—piston/rod, packings, seats/balls, etc.—are separate parts or come in different kits.

Always operate within the sprayer’s published maximum working pressure and follow the safety/maintenance guidance in the official Graco manual for your model.
