Ozone Generator Timer Knob – Replacement Part

This model is a replacement timer knob for an ozone generator with a mechanical timer dial (0–120 minutes). The original knobs on these devices often crack, get lost, or become loose over time. This replacement restores full usability of the device with a clean and simple design.

The knob fits the timer shaft well and provides a comfortable grip for setting the timer. The front pointer allows you to easily align the knob with the time markings on the ozone generator panel.

The fit is precise and secure, but for best long-term reliability it is recommended to apply a small drop of glue when installing the knob. Once mounted, it works smoothly and reliably.
