QS-001
Viqua QS-001 Quartz Sleeve is a replacement quartz sleeve, compatible with Viqua Sterilight S1Q-PA / VH200 / SSM-14 UV systems. Quartz sleeves should be replaced if they are cracked or chipped or if they remain cloudy or stained after cleaning.
This quartz sleeve is open on both ends. If your UV system uses a sleeve that is closed (domed) on on end, this is not the correct sleeve.
