No, this sleeve is designed for 18w, 24w, and 36w systems. It is not compatible with the 72w/110w units.
You should check it during every seasonal filter maintenance cycle, or whenever you notice a decrease in water clarity.
Body oils can create "hot spots" on the glass when heated by the UV lamp, which can lead to premature cracks.

The seal has likely failed. Inspect the O-rings for debris or damage and ensure the sleeve is tightened properly.
The sleeve may be clouded by limescale. Remove and clean with a mild vinegar solution, or replace if the glass is etched.
To install this sleeve, ensure the power is completely disconnected from the UVC unit. Carefully unscrew the existing housing, remove the old quartz sleeve, and clean any residual silicone or grime from the O-ring seat. Gently insert the new quartz sleeve, ensuring it is seated correctly within the rim.

Care Instructions: Always handle the sleeve with clean, dry hands. Fingerprints and oils can overheat the glass when the lamp is running. If the glass gets smudged, clean it with an alcohol-based glass cleaner before installation.
