Frequently Asked Questions
If the ring is missing or damaged, internal components may shift under pressure. That can lead to leaks, misalignment, or even failures in pumps or regulators.
No, not all Graco sprayers. The 113751 ring is used in specific assemblies like transfer pumps (e.g., T3) and back-pressure regulators. Always check your machine’s parts diagram or manual to confirm compatibility.
While it's possible, using a genuine Graco ring ensures the correct material, dimensions, and reliability. A non-OEM ring might not hold up under high-cycle or high-pressure use and could lead to performance issues.
