Trojan Sleeve - UVMax-5B, B4

This Trojan replacement quartz sleeve is made to fit UVMax-5B and UVMax-B4 ultraviolet disinfection systems, restoring the clear optical barrier that allows these units to work exactly as designed. In any UV system, the quartz sleeve is the precision component that houses and protects the UV lamp, keeping it completely dry while allowing the germicidal ultraviolet light to pass through into the surrounding flow of water. Because the light must travel through the sleeve to reach and treat the water, the optical clarity of that sleeve is absolutely fundamental to effective, reliable disinfection.

With normal use over time, quartz sleeves gradually develop a coating of mineral scale, iron, and film on their surface, and they can also crack from thermal stress or from handling during routine service. A fouled or damaged sleeve blocks UV light from reaching the water, which directly reduces the system's disinfection effectiveness and can allow microorganisms to slip through untreated. Swapping in a fresh, clean sleeve returns the system to full UV transmission so it can continue to address bacteria and other waterborne pathogens reliably and at its rated performance level.

• Maintains full UV light transmission into the water
• Protects and isolates the UV lamp from the water flow
• Genuine Trojan replacement component
• Lightweight at approximately 1.0 lb
• An essential part of routine UV system maintenance

Ultraviolet disinfection offers a dependable, chemical-free path to microbiologically safe water, and it is a longtime favorite for treating well water and other private supplies where pathogens may be present. Proper sleeve care is central to keeping that disinfection effective, so always handle the quartz gently and avoid touching the surface with bare hands during service, since the natural oils from skin can leave residue that impairs UV transmission. Consult your UVMax system manual for the recommended sleeve replacement interval and the correct installation procedure to maintain consistent, trouble-free performance. Because the sleeve and the lamp both affect how much germicidal energy reaches the water, many owners find it convenient to inspect and clean or replace the sleeve at the same time they perform their annual lamp change, addressing both critical components in one service visit and keeping the UVMax-5B or UVMax-B4 system operating at its full rated capability with minimal interruption to the water supply.
