The Waterway 602-4357 on and off valve turn knob is designed for compatible valve assemblies and comes in gray. A replacement knob like this is useful because it restores the part of the valve the user actually grips and turns, which can improve both usability and the finished appearance of the assembly.

The gray finish offers a more understated look that fits well in many spa and pool settings. When the original knob is damaged, faded, or missing, replacing it with the correct Waterway part can help bring the valve back to a more complete and serviceable condition.

For compatible valve repairs and refresh work, this Waterway turn knob is a practical solution when a neutral finish and improved handling are both desired.

  • Waterway on and off valve turn knob
  • Gray finish
  • Designed for compatible valve assemblies
  • Helps restore easier valve operation and cleaner appearance
  • Useful for repair and cosmetic replacement work
