About this product

Keep Your CT-500-UV System Running Efficiently with the Right Replacement Quartz Sleeve

The CT-500-UV Replacement Quartz Sleeve is a critical component of your ultraviolet (UV) water purification system. Designed specifically for the QMP CT-500-UV Water Purification system, this high-purity quartz sleeve provides a protective barrier around the UV lamp, ensuring maximum germicidal performance while shielding the lamp from water exposure and damage.

Over time, quartz sleeves can become clouded by mineral deposits or scratched during maintenance, reducing UV transmission. Replacing the sleeve restores the full disinfection power of your system—keeping your water safe, clean, and free from harmful microorganisms.

Installation tips

Unplug the CT-500-UV before opening the UV chamber—never service the unit while powered.
Allow the purifier to cool if it was recently in use.
Carefully remove the UV lamp first and set it aside safely (avoid touching the glass with bare hands).
Slide out the old quartz sleeve; be cautious, as sleeves may crack if mishandled.
Clean the sleeve housing before inserting the new quartz sleeve to ensure a proper seal.
Insert the new sleeve gently, making sure it is seated evenly and fully into position.
Reinstall the UV lamp, close the UV chamber, and plug the unit back in.
Run water through the system and confirm the UV indicator light activates.
Replace sleeves whenever they become cloudy, cracked, or mineral-coated, as this reduces UV effectiveness.

Frequently asked questions

How often should I replace the quartz sleeve?
We recommend replacing the quartz sleeve every 12–24 months, or sooner if it becomes stained or cloudy. A dirty sleeve can significantly reduce UV performance.

Is this sleeve compatible with other UV systems?
It is specifically designed for the CT-500-UV system. While it may fit others with similar dimensions, always check your manufacturer’s specs.

Do I need to turn off the system before replacing the sleeve?
Yes. Always disconnect power and shut off water flow before performing maintenance to prevent electrical shock or water damage.

Does this include the UV lamp?
No. This listing is for the quartz sleeve only. UV lamps are sold separately.

What happens if I continue using a cloudy or cracked quartz sleeve?
It will block UV light from reaching the water, reducing disinfection efficiency and potentially compromising water safety.

Can I clean a quartz sleeve instead of replacing it?
Light mineral deposits can sometimes be cleaned, but if the sleeve remains cloudy or scratched, it must be replaced to maintain UV performance.

Is the quartz sleeve the same as the UV bulb?
No. The quartz sleeve protects the UV bulb from water and allows UV light to pass through. The bulb and sleeve are separate components.
