About This Item

OEM Replacement Seal Kit for the Pentair BioShield UV System

The Pentair BioShield UV Seal Kit (523383Z) is the OEM replacement seal kit for the BioShield UV sanitizer system. When seals within the UV unit begin to degrade, this kit provides the correct replacement components to restore a watertight, properly functioning assembly.

⚠️ IMPORTANT: THIS LISTING IS A KIT
This listing includes a complete seal kit — not a single seal. Confirm that all components in this kit are required for your service before ordering.

What It Does

The seals within a UV sanitizer system prevent water from migrating past internal lamp and chamber interfaces. Replacing worn or damaged seals with this OEM kit restores the integrity of the BioShield UV housing and ensures the system continues to operate at its rated sanitizing capacity. Match part number 523383Z to the number on your existing components before ordering.

Pro Tip

When servicing the BioShield UV system, inspect the UV lamp and quartz sleeve at the same time. Seals and lamps often reach end-of-service life on similar intervals — replacing both during the same service visit avoids a repeat disassembly. Verify the part number on your existing seal components matches 523383Z before ordering.
