The Waterway 718-4320 manifold nut is designed for compatible Crystal Water filter manifold applications. A manifold nut is a small but important service part because it helps secure the internal assembly properly and contributes to the overall stability of the filter’s internal structure.

When a nut becomes cracked, stripped, or missing, the surrounding assembly can be harder to trust during reassembly. Replacing it with the correct Waterway part helps restore a more complete and serviceable internal fit without relying on mismatched hardware.

For compatible Crystal Water filter maintenance, this Waterway manifold nut is a practical replacement component that helps support cleaner and more dependable internal reassembly.
