Description
RK2/XFLO Quartz Sleeve U200000-25MM-1334D | 25 mm Diameter Quartz Sleeve • Approx. 1334 mm Length (~52.5″) • OEM Replacement for XFLO/RK2 UV Systems
The U200000-25MM-1334D quartz sleeve is a high-quality replacement part tailored for specific XFLO/RK2 UV steriliser models using a 25 mm diameter sleeve and longer lamp arc lengths. With a length of approximately 1334 mm, it fits large-format reactors and ensures the UV lamp remains properly shielded while enabling optimal UV-C light transmission.
Key Features
-
25 mm outer diameter – matches the sleeve specification for XFLO/RK2 systems demanding this size.
-
Approx. 1334 mm length (~52.5″) – accommodates reactors with extended lamp arcs; suitable when standard shorter sleeves won’t suffice.
-
Hard-quartz glass construction – designed to maximise UV-C transmission, resist scaling, and tolerate harsh aquatic environments.
-
OEM-compatible part – specified for XFLO/RK2 units, ensuring correct fit, alignment and performance when replacing the original sleeve.
-
Maintains steriliser efficiency – preserving clear quartz means the UV lamp can deliver the intended dose, critical for water clarity and pathogen control.
Technical Specifications
| Specification | Value |
|---|---|
| Part Number | U200000-25MM-1334D |
| Diameter | 25 mm outer diameter |
| Length | ~1334 mm (~52.5″) |
| Material | Hard quartz (UV-C transmissive) |
| Typical Use | XFLO / RK2 UV reactors requiring long sleeves |
Applications
-
Replacement sleeve for large diameter or high-wattage XFLO/RK2 UV reactors that originally used a ~1334 mm sleeve.
-
Aquariums, ponds or aquaculture systems where the UV steriliser has a long lamp arc and the original sleeve length must be matched for proper UV exposure.
-
Maintenance inventory for service technicians working on XFLO/RK2 systems to ensure quick replacement of quartz sleeves when clouding or damage occurs.
Benefits
-
Helps restore full UV-C exposure by replacing old or fouled quartz sleeves, thus ensuring your UV steriliser continues to deliver effective microbial inactivation.
-
OEM specification reduces risk of mis-fit, mis-alignment or performance drop-out that might occur with generic sleeves.
-
Long-length design accommodates large-scale systems—ideal for installations with higher lamp length or larger vessel geometry.
-
Enhances water clarity and system reliability by maintaining the designed sleeve dimensions and specifications.
Installation & Maintenance Tips
-
Depressurise and power off the UV steriliser before removing the old quartz sleeve.
-
Replace O-rings or seals concurrently, as wear or damage here can result in leaks or reduced sleeve stability.
-
Inspect the new sleeve for any scratches, chips or residues. Clean it (e.g., with isopropyl alcohol) avoiding bare-hand contact with the quartz surface.
-
Install the sleeve carefully, ensuring proper orientation, alignment and that it seats correctly in the chamber.
-
After installation, inspect the assembly for leaks and ensure the lamp operates properly. Regularly monitor the sleeve: if clouding, scaling or deposits appear, clean or replace to maintain UV output.
Summary
The Quartz Sleeve U200000-25MM-1334D is a specialised maintenance component engineered for XFLO/RK2 UV steriliser systems that require a long-length, 25 mm diameter quartz sleeve. By matching the OEM specification, it helps maintain the designed UV-C dose, supports optimal water clarity, and ensures reliable operation in demanding aquatic and pond applications.
