Frequently Asked Questions
The spring cap protects and holds the spring mechanism in place, maintaining correct preload and alignment for reliable system operation.
Replace the cap during major servicing or if you notice that the spring is not being properly held, the cap is damaged, or alignment issues appear in the mechanism.
The original 15A172 ensures the correct material, fit, and function as designed by Graco. Using a non‑OEM cap may lead to misalignment, spring load drift, or premature wear of other components.
