QJ25680 Compatible Quartz Sleeve for SUV-S-30-3/4 - (Open Ended)

This is a compatible open-ended quartz sleeve for the SUV-S-30-3/4 UV disinfection system, supplied by WrekinWater as part code QJ25680. The SUV-S-30-3/4 is the largest-flow Sabre unit in this range, typically used where a household or small commercial site needs a higher throughput than the SUV-S-4 or SUV-S-8 provide. This sleeve is sized to match that larger chamber and lamp.

Signs your quartz sleeve needs replacing

• The sleeve is visibly cloudy, scaled or scratched rather than glass-clear.
• A brown or yellow deposit has formed that will not lift off with a light wipe.
• The SUV-S-30's UV monitor is showing a low-dose or fault warning.
• The sleeve is around 12 months old, the usual interval before performance starts to drop.

On the SUV-S-30-3/4, this sleeve keeps the lamp dry while letting its UV output reach the largest water flow of any unit in this range. Because more water passes through per minute here than on the SUV-S-4 or SUV-S-8, any scaling or scratching that reduces UV transmittance on the sleeve has a bigger practical impact on treated water quality, even while the lamp continues to light and run normally.

WrekinWater supplies this compatible sleeve matched to the SUV-S-30-3/4's larger chamber, drawing on 15 years of sourcing parts across major UV brands. We are rated Excellent on Trustpilot and can confirm the correct fit for your specific Sabre model before you order.
