G-QS-200 Replacement Sterilight QS-200 Quartz Sleeve for SP200-HO

Keep your UV water treatment system performing at its best with the G-QS-200 Replacement Quartz Sleeve, a premium compatible replacement for the Sterilight QS-200. Manufactured from high-quality fire-polished fused quartz, this sleeve delivers exceptional UV light transmission while protecting the UV lamp from direct contact with water.

Designed for Sterilight SP200-HO ultraviolet systems, this replacement sleeve features a closed (domed) end and is supplied complete with two replacement O-rings for a secure, leak-free installation. It is also compatible with several other Sterilight/Viqua systems using the QS-200 sleeve.

Over time, mineral deposits such as limescale, iron and manganese can accumulate on the quartz sleeve, reducing UV light transmission and lowering the effectiveness of your UV disinfection system. Regular cleaning and scheduled replacement help maintain optimum sterilisation performance.
