The Waterco Hydro II TM hub assembly with laterals is designed for compatible 18 inch and 21 inch filter applications where the internal collector hub and lateral structure need replacement. An assembly like this is useful because it restores a major internal section of the filter in one coordinated component rather than requiring multiple separate internal parts to be sourced and matched.

This replacement is especially useful when the original hub or laterals are cracked, broken, or too worn to justify partial repair. Replacing the assembly as a unit can make the rebuild feel more complete and help preserve proper internal geometry inside the filter.

The 15B0128 is a strong service choice when a compatible Waterco Hydro II TM filter needs its internal hub and laterals renewed for more dependable performance.

  • Designed for compatible 18 inch and 21 inch filters
