Luminor RQ-1000 Sleeve for LR5-851, LR6-851, LR5-1751
Luminor RQ-1000 Sleeve for LR5-851, LR6-851, LR5-1751
Description
The RQ-1000 is a genuine Luminor replacement quartz sleeve for LUMINOR RAINIER LR5-851, LR6-851, LR5-1751, and LR6-1751 light commercial systems, plus their low-UVT (-50) and total organic carbon (TOC) variants below. It's an authentic Luminor part, not an aftermarket substitute, so your system keeps performing the way it was tested and certified.
Fits these Luminor Rainier systems
- LR5-851 (85 GPM)
- LR6-851 (85 GPM)
- LR5-851-50 (low-UVT crossover)
- LR6-851-50 (low-UVT crossover)
- LR5-851-TOC (total organic carbon reduction)
- LR6-851-TOC (total organic carbon reduction)
- LR5-1751 (175 GPM)
- LR6-1751 (175 GPM)
- LR5-1751-50 (low-UVT crossover)
- LR6-1751-50 (low-UVT crossover)
- LR5-1751-TOC (total organic carbon reduction)
- LR6-1751-TOC (total organic carbon reduction)
The 85 GPM "-851" tier uses 1 sleeve per system; the 175 GPM "-1751" tier uses 2. The final digit reflects electrical cord configuration, not a different part, so every variant above uses the identical RQ-1000.
Why a genuine Luminor sleeve matters
Luminor certifies its UV systems as a complete lamp, chamber, and sleeve unit. A non-Luminor sleeve can differ in wall thickness or quartz quality, reducing UV-C output reaching the water and affecting your warranty coverage.
Complete your replacement
- Luminor RL-1000A UV Replacement Lamp, the standard lamp for this sleeve. Replace every 12 months, or after 12,000 hours. TOC models use a separate RL-1000A-TOC lamp; contact us to source one.
- Luminor RLQ-1000A UV Lamp and Sleeve Kit, which bundles the RL-1000A lamp and RQ-1000 sleeve together.
- Replace every 24 months or as needed
- Length: 44.68" (1135mm)
- Style: Open

More product information
Q:
Does the RQ-1000 fit the low-UVT and TOC versions of my system, or just the standard LR-851/LR-1751?
A:
It fits all of them. The low-UVT ("-50") and TOC variants of both the 85 GPM and 175 GPM tiers use the same chamber and sleeve as the standard systems; only the lamp and the system's internal dose settings change between variants.
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-1000 is the sleeve only. If your lamp is also due, pair it with the [RL-1000A](https://espwaterproducts.com/products/luminor-rl-1000a-uv-replacement-lamp) lamp, or save by ordering the [RLQ-1000A](https://espwaterproducts.com/products/luminor-rlq-1000a-uv-lamp-and-sleeve-kit-for-lr6-855-1755-lk6-a22-a42-a62) kit, which bundles both.
Q:
Can I use a non-Luminor sleeve instead of the RQ-1000?
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:
Why does the sleeve need replacing on a different schedule than the lamp?
A:
The lamp is a wear part rated for 12,000 hours, so it's replaced on a fixed schedule (about every 12 months). The sleeve doesn't burn out the same way; it fouls from mineral scale and staining, which is why its replacement guidance is calendar-based (every 24 months) rather than hour-based.
