Frequently Asked Questions

The connecting rod links the pump’s drive mechanism to the fluid piston, converting rotary or reciprocating motion into axial stroke motion for fluid pressurization.

This rod is designed specifically for the President 55 G series pump models listed above. Fitment with other Graco pump families should be verified against the service parts manual.

Regular inspection for scoring or corrosion and ensuring proper lubrication at connecting points helps extend service life.
