The J300 / J400 / J-LX Diverter Knob is a genuine Jacuzzi® replacement control is designed to restore smooth and precise water flow adjustment in compatible hot tubs. Because the diverter knob is handled regularly, it can become worn, faded, cracked, or loose over time. Replacing it ensures your spa maintains both full functionality and a clean, factory-finished appearance. Restore Smooth Water Flow Control The diverter knob allows you to redirect water between different jet zones within your Jacuzzi® hot tub. When the knob becomes damaged or worn, operation can feel stiff or unstable. In addition, a deteriorated knob can detract from the overall look of your spa controls. By installing a genuine J300 / J400 / J-LX Diverter Knob, you restore confident grip, smooth rotation, and accurate water distribution across jet systems. As a result, you regain full control of your hydrotherapy experience. Designed for J-300™, J-400™ and J-LX® Models This diverter knob is manufactured to genuine Jacuzzi® specifications for compatible J-300™, J-400™, and J-LX® models. Therefore, it fits correctly onto the original diverter valve stem when matched to the correct spa model and year. However, always confirm compatibility with your specific Jacuzzi® hot tub before ordering to ensure correct fitment. Durable Spa-Grade Construction Hot tub controls are exposed to heat, moisture, and sanitising chemicals. For this reason, genuine Jacuzzi® diverter knobs are produced from high-quality, spa-grade materials designed to resist fading and cracking. This ensures long-term durability while maintaining the premium finish expected from a Jacuzzi® spa. Choosing genuine parts also helps protect the internal diverter mechanism from unnecessary strain caused by poor fitting alternatives.
