Product information
A 33-inch quartz sleeve for UV-C sterilizer chambers using the 40W, G10q 4-pin lamp format — the same size as our Philips and generic 33-inch UV lamps and our 33-inch stainless steel UV sterilizer. The sleeve sits between the lamp and the water flow: it keeps the lamp itself completely dry while still letting UV-C light pass through, since ordinary glass blocks UV-C but quartz doesn't.
The sleeve is what actually contacts the water — the lamp never does. Mineral scale from hard water builds up on the sleeve's outer surface over time and blocks UV-C transmission even if the lamp itself is still working, which is why the sleeve needs its own cleaning and eventual replacement schedule, independent of the lamp.

| Material | Fused quartz glass |

Wipe the sleeve clean periodically, especially in hard-water areas where scale forms fastest — a visibly cloudy or scaled sleeve is blocking UV-C output even if the lamp itself is fine. Handle it carefully during installation: quartz is more brittle than ordinary glass and can crack if dropped or over-tightened.
