Protect Your UV Investment
This genuine VIQUA 602733 quartz sleeve is the critical barrier between your UV lamp and the water. Made from high-purity fused silica, it allows 100% of the UV-C light to pass through while protecting the lamp from water damage and temperature fluctuations.

Why Genuine Matters
Using a genuine VIQUA sleeve ensures a perfect physical fit and thermal stability. Generic sleeves often use lower-grade glass that blocks UV light or fails to maintain the high operating temperature required for proper disinfection.

Maintenance Note
Mineral buildup (scale) on the sleeve will block UV light. Clean the sleeve regularly. If it remains cloudy after cleaning, or if you find any chips or cracks, it must be replaced immediately to ensure your water is safe.
