About This Item

The 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. Replacing this sleeve with the correct OEM part restores full UV intensity and protects the lamp from premature failure caused by water exposure.

Pentair BioShield 522637 Quartz Sleeve 50.75"

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Poolaroo Pro Tip

Inspect the quartz sleeve for cloudiness, mineral scale, or hairline cracks whenever you service the UV lamp. Even a sleeve that appears intact can lose significant UV transmittance from mineral buildup over time. Clean the sleeve with a soft cloth and a diluted acid wash approved for quartz before reinstalling — or replace it if pitting or discoloration is present. Handle the sleeve with clean, dry gloves; skin oils can etch the surface and reduce clarity under UV exposure.
