The CMP Hydroseal diverter valve knob is designed for compatible valve applications where the supported user-control knob needs replacement. A knob is useful because it gives the user a direct way to operate the valve, helping restore proper manual adjustment without replacing the full valve assembly.

This replacement is especially useful when the original knob is cracked, loose, worn, or missing. Matching the correct black replacement knob helps preserve intended fit and supports a cleaner-looking control restoration.

The 25913-204-070 is a practical service part when a compatible CMP Hydroseal diverter valve needs a knob to restore dependable manual operation.

  • CMP Hydroseal diverter valve knob
  • Black finish
  • Designed for compatible valve-control applications
