What Does the Quartz Sleeve Do?
The quartz sleeve forms a protective barrier between the UV lamp and the water flowing through the treatment chamber. It prevents the lamp from coming into direct contact with water while allowing germicidal UV-C energy to pass through the chamber.
The sleeve also helps the UV lamp maintain the proper operating temperature needed for consistent system performance.
Cleaning and Replacement
Minerals and other deposits can accumulate on the quartz sleeve over time. This buildup can block UV-C energy and reduce the system’s ability to treat water effectively.
Inspect and clean the quartz sleeve during routine UV lamp maintenance. Replace the sleeve if it is:
- Chipped or cracked
- Scratched or otherwise damaged
- Permanently cloudy
- Discolored or stained after cleaning
Always handle the quartz sleeve carefully. Avoid touching it with bare hands, and follow the maintenance instructions provided with your UV system.
Verify Before Ordering
Check the label on your UV chamber or confirm the existing sleeve number before ordering. Choose the RQ-420 if your system or current sleeve is identified by one of the following numbers:
- Aquasana AQ-UV-15C
- Aquasana AQ-UV-Q420
- LUMINOR LBH4-151
- LUMINOR LBH5-151
- LUMINOR LBH6-151
- LUMINOR RQ-420
This listing is for the replacement quartz sleeve only. The UV lamp and other system components are sold separately unless expressly stated otherwise.

Q&A
Q:
Does the RQ-420 fit my standard BLACKCOMB system or only BLACKCOMB-HO?
A:
Both. The RQ-420 is used across the standard BLACKCOMB LB5-081 and rack Z-series, the BLACKCOMB-HO LBH4/5/6-151 line (including HW, low-UVT, and TOC variants) and its own rack Z-series, and the Contractor Series. Only the lamp changes between the standard and High Output lines; the sleeve is the same.
Q:
How do I know if I need to clean the sleeve or replace it?
A:
Clean it if it's scaled or lightly stained; replace it if it's scratched, pitted, or stays cloudy after cleaning. Even with no visible damage, Luminor recommends replacing the sleeve every 24 months as routine maintenance, since UV-C transmission through quartz declines gradually with age.
Q:
Do I need to buy the lamp too, or can I just replace the sleeve?
A:
The RQ-420 is the sleeve only. Standard BLACKCOMB systems use the [RL-420](https://espwaterproducts.com/products/luminor-rl-420-replacement-uv-lamp) lamp or [RLQ-420](https://espwaterproducts.com/products/luminor-rlq-420-uv-lamp-and-sleeve-replacement-kit) kit; BLACKCOMB-HO systems use the [RL-420HO](https://espwaterproducts.com/products/luminor-rl-420ho-high-output-replacement-uv-lamp) lamp or [RLQ-420HO](https://espwaterproducts.com/products/luminor-rlq-420ho-uv-lamp-and-sleeve-replacement-kit) kit.
Q:
Can I use a non-Luminor sleeve instead of the RQ-420?
A:
You can, but it's not recommended. Luminor certifies its systems as a complete lamp-chamber-sleeve unit, and a non-Luminor sleeve can differ in wall thickness or quartz quality, which reduces the UV-C dose reaching the water and can affect your warranty coverage.
Q:
Does the RQ-420 work with my Aquasana system?
A:
If your Aquasana system is the AQ-UV-15C, yes. The RQ-420 is a confirmed genuine Luminor replacement for its AQ-UV-Q420 sleeve.
