The Grid Controls 3-Way Valve Seal Retainer is a replacement retaining component used inside compatible Grid Controls 3-way diverter valve assemblies. It is intended for repairs where the valve needs to hold the internal seal or gasket in proper position so water can be routed more consistently through the selected plumbing path. This type of part is useful when rebuilding a diverter rather than replacing the entire valve body, especially when the surrounding plumbing is still serviceable. Before ordering, compare the existing retainer, valve style, and part number 3006 to confirm the repair matches your Grid Controls assembly. Replacement seal retainer for compatible Grid Controls 3-way diverter valves Helps keep the valve seal positioned correctly during operation Useful for valve rebuilds where the main body remains in good condition Check the existing valve style and part number before installation Best suited for service technicians and detailed plumbing repairs
