The Viqua 602732 Quartz Sleeve is the ideal thermal protection for the UV bulb in Viqua D4, D4+, D4-V, IHS12-D4 and D4-V+ systems as well as the discontinued Trojan C, C4, and C4-V UV systems.
The Viqua Quartz Sleeve provides thermal protection to your ultraviolet lamp ensuring the disinfection system continues to optimally reduce bacteria and viruses in the water. For best results, this sleeve should be cleaned on a consistent basis after installation. Replace this sleeve in the event of damage or fouling.
The replacement sleeve does not include a Part No. 410867 O-ring which is a separate item that may be required.
