The Val-Pak generic PacFab 2 inch slide valve piston gasket is designed for compatible valve applications where the internal piston sealing surface needs to be refreshed. In a push-pull or slide valve, the piston gasket is one of the parts that has the most direct impact on how well the valve operates and how confidently it controls flow.This replacement is especially useful when the original gasket is worn, cut, hardened, or no longer sealing as the piston moves through the valve body. Replacing the gasket can often restore a noticeable improvement in valve feel and function without requiring a complete valve replacement.The V36-110 is a practical choice when a valve rebuild calls for targeted internal service and the goal is to restore proper piston sealing with the right part.
