Jacuzzi® J-300 Series Diverter Knob – Grey Replacement (2002–2006)

Restore precise water flow control in your spa with the Jacuzzi® J-300 Series Diverter Knob – Grey (6540-728). Designed for 2002–2006 Jacuzzi J-300 Series models, this replacement knob allows you to smoothly redirect water between jet zones, helping customize massage pressure and overall hydrotherapy performance.

Diverter knobs are frequently handled and exposed to heat, chemicals, and UV, which can cause fading, cracking, or stiffness over time. Replacing a worn or damaged knob improves ease of use, restores proper valve operation, and refreshes the look of your spa’s control area - without replacing the entire diverter valve.

Manufactured for a precise fit on compatible Jacuzzi diverter valves, this grey knob is ideal for routine maintenance or cosmetic refurbishment.

Features:
- Replacement diverter knob for Jacuzzi® J-300 Series spas
- Compatible with 2002–2006 models
- Allows smooth redirection of water flow between jet zones
- Durable, spa-grade construction resistant to heat and chemicals
- Ideal replacement for cracked, faded, or hard-to-turn knobs
