Frequently Asked Questions

It acts as a spring/roll pin to retain and align internal parts (commonly in the piston/valve or rod assembly). Proper retention prevents misalignment and wear.

Check your pump’s parts manual or schematic. If the list shows Graco 102180 (or a 0.135" × 1" roll pin) for your assembly position, it’s the correct part.

Use OEM parts whenever possible. If substituting, match both diameter and length exactly and verify fit and function per the service manual.

Replace it any time it’s removed, bent, fatigued, or shows wear. A fresh 102180 ensures proper retention after reassembly.

No. Align the components, then drive the roll pin squarely into place using proper support. Verify seating and free movement of the assembly afterward.
