G-QS-212 Replacement Sterilight QS-212 Quartz Sleeve for SQ-PA

The G-QS-212 Replacement Quartz Sleeve is a high-quality compatible replacement for the Sterilight QS-212, designed to restore the performance of your UV water steriliser.

Suitable for a wide range of Sterilight, Viqua, R-Can and Evoqua UV systems, this replacement sleeve features an open both ends design and is supplied complete with two replacement O-rings for a secure, leak-free installation.
