Description
RK2/XFLO Quartz Sleeve U200000-25MM1016D | 25 mm Diameter Quartz Sleeve • 1016 mm Length (~40″) • Replacement Sleeve for XFLO UV Systems
The U200000-25MM1016D quartz sleeve is a precision-made replacement component designed for use in XFLO UV steriliser systems. With a 25 mm outer diameter and approx. 1016 mm length (40 inches), it fits select 3″ and 5″ diameter UV reactor vessels that require long quartz sleeves. It’s an essential maintenance part for maintaining optimum UV-C exposure and sterilisation performance in your system.
Key Features
-
25 mm quartz sleeve diameter — perfectly matched for systems specifying a 25 mm internal sleeve.
-
Approx. 1016 mm (40″) length — suitable for reactors that accommodate long-arc lamps or extended exposure designs.
-
High-quality hard-quartz material — engineered to maximise UV-C transmission while resisting thermal and chemical stresses.
-
OEM replacement part — listed in the XFLO / RK2 replacement parts manual as part number U200000-25MM1016D.
-
Maintains system performance — ensures that your UV reactor continues to deliver the correct dose by preserving transparency and protecting the UV lamp from direct water contact.

Applications
-
Replacement quartz sleeve for XFLO UV steriliser units after lamp replacement or when sleeve becomes fouled or damaged.
-
Suitable for installations where transparency and UV transmission must remain high for effective sterilisation.
-
Ideal for use by aquarium, pond or industrial water treatment professionals maintaining RK2/XFLO systems.
Benefits
-
Helps maintain effective UV-C dose by ensuring the UV lamp is properly sealed and the water flow path remains clear of outer collisions.
-
Protects the UV lamp from direct exposure to the water flow, reducing lamp fouling and enabling longer lamp life.
-
Keeps your steriliser operating at design specifications—crucial for clarity, pathogen control and system reliability.
-
OEM-matched component ensures compatibility and simplifies sourcing for maintenance.
Installation & Maintenance Tips
-
Always power off and depressurise the UV reactor prior to sleeve removal and replacement.
-
Clean or replace the O-ring seals when replacing the sleeve to ensure leak-free performance.
-
Inspect the quartz sleeve regularly—if you observe clouding, deposits or scale, clean it or replace it to maintain UV transmission.
-
Avoid touching the quartz surface with bare hands—skin oils can reduce UV transmission through the sleeve.
-
After installation, inspect for leaks, ensure flow path is correct, and monitor system performance as per the manufacturer’s schedule.
The U200000-25MM1016D is a crucial maintenance component for XFLO/RK2 UV steriliser systems requiring a 25 mm diameter quartz sleeve approximately 1016 mm in length. Using this OEM-specified sleeve helps ensure your UV system continues to operate at peak performance, delivering the required sterilisation dose and longevity of the lamp and reactor.
