G-QS-212D Replacement Sterilight QS-212D Quartz Sleeve for SC1
Restore the performance of your UV water treatment system with the G-QS-212D Replacement Quartz Sleeve, a high-quality compatible replacement for the Sterilight QS-212D. Manufactured from premium fire-polished fused quartz, this sleeve provides excellent UV light transmission while protecting the UV lamp from direct contact with water, ensuring your UV system continues to operate at maximum efficiency.
Designed specifically for Sterilight SC1 ultraviolet systems, the G-QS-212D features a closed (domed) end and is supplied complete with two replacement O-rings for a secure, leak-free installation.
Over time, limescale, iron, manganese and other mineral deposits can accumulate on the quartz sleeve, reducing UV light penetration and lowering the effectiveness of your UV disinfection system. Regular cleaning and scheduled replacement help maintain reliable protection against bacteria, viruses and other harmful microorganisms.
