QJ25330 - Compatible Quartz Sleeve for SUV-S-8 -1/2 (Open Ended)

This is a compatible open-ended quartz sleeve for the Spectrum Sabre SUV-S-8-1/2 UV disinfection system, supplied by WrekinWater as part code QJ25330. The SUV-S-8-1/2 handles a higher flow than the SUV-S-4-1/4, and unlike the domed SUV-S-4 sleeve, this one is open at both ends, fitting between two seals within the housing. It is a direct consumable replacement for the original Sabre sleeve.

Signs your quartz sleeve needs replacing

• The sleeve has become cloudy, hazy or visibly scratched along its length.
• There is a brown or yellow discolouration that will not wipe off.
• The SUV-S-8's UV monitor has flagged a low-intensity condition.
• The sleeve has done about 12 months of service, the standard point to renew it.

The sleeve on the SUV-S-8-1/2 protects the lamp from direct contact with the water passing through at this unit's higher flow rate, while still allowing UV light through the quartz wall to disinfect it. As scale and fine scratching accumulate on an open-ended sleeve like this, UV transmittance drops steadily, and because more water is passing through per minute than on the smaller SUV-S-4, that drop affects a larger volume of treated water for the same level of fouling.

WrekinWater supplies this compatible sleeve matched to the SUV-S-8-1/2's higher-flow chamber, built on years of experience sourcing parts for Spectrum Sabre and other UV brands. We are rated Excellent on Trustpilot and can help confirm your exact Sabre model before you order.

How to replace it

1. Isolate the water supply to the SUV-S-8 unit and switch off power at the mains.
2. Undo the retaining nut or union and withdraw the lamp from the housing.
3. Slide the old QJ25330 sleeve out from the housing.
4. Wipe out the housing and fit new O-rings at both ends before fitting the replacement.
5. Insert the new sleeve, refit the lamp, and reassemble the housing.
6. Restore water and power, then flush the system briefly to drain before use.
