About This Item
The Pentair BioShield Quartz Sleeve (523040) is the OEM replacement quartz sleeve for the Pentair BioShield UV System 80 Watt (Model 522636), measuring 38-1/4" in length.
What It Does
The quartz sleeve surrounds the UV lamp inside the BioShield system, creating a protective barrier between the lamp and the water flow while allowing ultraviolet light to pass through. A compromised or fouled sleeve reduces UV transmission efficiency, diminishing the system's ability to inactivate microorganisms. Replacing a cracked, etched, or mineral-scaled sleeve restores full UV output and protects the lamp from direct water contact.

Pro Tip
Quartz sleeves should be inspected at least annually. Mineral scale and biofilm accumulation on the sleeve surface block UV transmission even when the lamp itself is functioning correctly — a visually cloudy or etched sleeve warrants replacement regardless of lamp hours. When servicing the sleeve, inspect the sleeve O-rings and lamp at the same time; replacing all wear components in a single service visit minimizes system downtime. Confirm the 38-1/4" length against your existing sleeve before ordering — the BioShield line includes multiple sleeve lengths across different wattage models.
