Pentair Quartz Sleeve 50.75" | BioShield UV System | 523041 Pool Liner Accessories or deterioratedThe Pentair Quartz Sleeve (523041) is the OEM replacement quartz sleeve for the Pentair BioShield UV System 120 Watt (Model 522637), measuring 50. 75 inches in length. The quartz sleeve surrounds the UV lamp inside the BioShield sterilizer, transmitting ultraviolet light into the water flow while isolating the lamp from direct water contact. A cracked, clouded, or mineral scaled sleeve reduces UV transmittance and compromises disinfection output.
