We are pleased to offer a complete selection of replacement quartz sleeves for all Viqua (Trojan) UVMax ultraviolet (UV) sterilizers.

Viqua (Trojan) UVMax Model #602731 replacement sleeves are designed only for use in Viqua (Trojan) UVMax UV sterilizers. We do not recommend that you attempt to use Trojan replacement sleeves in models made by other manufacturers.

It is critical that only genuine UVMax brand original equipment sleeves be used in your system. It has come to our attention that a number of Chinese manufacturers are making knock-off replica UV sleeves. While they may physically fit in a UVMax system, they are NOT compatible. Testing of a wide range of these sleeves has shown that many do not allow a safe UV dose to pass through the sleeve and may be subject to failure.

UVMax #602731 is the sleeve for the following models:

• Viqua (Trojan) UVMax Model B/B4

Viqua UVMax #602731 Sleeve Customer Questions & Answers

Question:	Does this come with the O-rings
Answer(s):	Yes, all Viqua sleeves and lamp / sleeve combos come with the necessary o-rings By HomePlus Water on Feb 15, 2024

It is critical that only genuine Viqua brand original equipment lamps be used in your system. It has come to our attention that a number of Chinese manufacturers are making knock-off replica UV lamps. While they may physically fit in a Viqua system, they are NOT compatible. Testing of a wide range of these lamps has shown that many do not provide a safe UV dose or offer protection for the stated lamp life, and in some cases have even caused the failure of the ballast/controller and melting of the lamp harness.
