The Waterway 602-4351 on and off valve turn knob is designed for compatible valve assemblies and features a black finish. The turn knob is the part the user interacts with directly, so replacing a damaged one can make a major difference in how easy and satisfying the valve is to operate.

When the original knob becomes cracked, worn, or difficult to grip, the valve may still function internally but feel less dependable in real-world use. Using the correct Waterway replacement helps restore a more finished appearance and better day-to-day handling.

For compatible valve service and cosmetic refresh projects, this Waterway turn knob is a practical replacement when a black finish and improved operator feel are the goals.

  • Waterway on and off valve turn knob
  • Black finish
  • Designed for compatible valve assemblies
  • Helps restore easier and cleaner valve operation
  • Useful for service, repair, and appearance refresh work
