Product Description
If your Yamitsu UV isn’t performing as it should, a cloudy or cracked quartz sleeve can reduce UV output. The Quartz Sleeve (6w / 11w Yamitsu) is a replacement glass sleeve designed to fit 6 watt and 11 watt Yamitsu UV units.
The quartz sleeve protects the UV lamp from direct contact with pond water while allowing ultraviolet light to pass through efficiently.
Why it matters
- Protects the UV-C lamp from water exposure
- Maintains correct UV transmission
- Supports effective algae control
- Essential for safe UV operation
A damaged or heavily scaled sleeve reduces UV performance, even if the lamp itself is working.
When to replace
Consider replacement if you notice:
- Cracks or chips in the glass
- Heavy mineral scaling that won’t clean off
- Water inside the UV housing
- Reduced clarity despite a new lamp
Installation & Safety
- Always unplug the UV unit before servicing.
- Allow the lamp to cool before handling.
- Handle the quartz sleeve carefully — it is fragile.
- Check O-rings and seals during reassembly.
Replacing a worn quartz sleeve helps restore proper UV performance and keeps your Yamitsu unit operating safely and effectively.
