Frequently Asked Questions
A worn pivot pin can cause the clamp to loosen, misalign, or fail to lock properly, which could lead to hopper detachment or leaking. Replacing it restores clamp stability.
While a generic pin may physically fit, using the OEM 15B926 ensures the correct dimensions, material hardness, and precise fit for reliable clamp operation in Graco systems.
Check your parts diagram or your sprayer manual — in many Graco T2-style hopper systems, the 15B926 is listed as the pivot pin for the clamp assembly.
