Frequently Asked Questions

The Graco 15A119 piston is used in D20 displacement pump assemblies (models 245351 and 245639), offering reliable fluid transfer and pressure control.

First, make sure the system is fully depressurized. Clean the pump lower housing, then carefully insert the 15A119 piston ensuring proper alignment. Finally, evenly torque down the housing bolts.

Inspect the piston regularly for wear, scoring, or damage. If performance degrades, or if the piston shows visible wear, replacing it with a new OEM part can restore optimum function.
