Not sized for Aqua Ultraviolet's Classic series or for other brands' UV sterilisers – check your unit's model and wattage before ordering, since sleeve diameters differ across the Aqua Ultraviolet range.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cp\u003eOne quartz sleeve only. The UV lamp, unit housing, O-rings and end caps are not included – order these separately if they also need replacing.\u003c\/p\u003e\n\n\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\n\u003ch4\u003eWhen should I replace the sleeve rather than just clean it?\u003c\/h4\u003e\n\u003cp\u003eWipe the sleeve down each time you change the lamp. Replace it outright if it's visibly scratched, chipped, or permanently hazed with limescale that won't wipe off – all three block UV-C output even with a fresh lamp fitted.\u003c\/p\u003e\n\u003ch4\u003eHow do I clean it in the meantime?\u003c\/h4\u003e\n\u003cp\u003eWipe with a soft cloth; a mild vinegar soak lifts mineral scale without scratching the quartz. Avoid abrasive pads, which score the surface and reduce UV-C transmission permanently.\u003c\/p\u003e\n\n\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\n\u003cp\u003eSold as a genuine Aqua Ultraviolet spare part.
