Description
The Viqua S463‑QL UV Lamp & Quartz Sleeve Combo is a genuine Viqua/Sterilight replacement lamp and quartz sleeve kit designed to keep your UV water disinfection system operating at peak performance. This combo pack includes both the standard-output UV lamp (S463RL) and the QS-463 quartz sleeve, delivering the essential components needed for annual maintenance or mid-life service.
The quartz sleeve surrounds the UV lamp inside the reactor chamber, protecting the lamp from water exposure while allowing germicidal UV-C light to pass through unobstructed. Replacing both the lamp and quartz sleeve ensures your system continues to deliver effective, chemical-free disinfection against harmful microorganisms such as bacteria, viruses, and protozoa.
