About This Item

The Pentair 4 in. Lens Gasket (79108500Z) is the OEM replacement gasket for the SpaBrite underwater pool light. This off-white gasket seals the 4 in. diameter lens assembly, preventing water intrusion into the light housing.

IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Pool lighting components operate in wet environments. Installation must comply with NEC Article 680 and be performed by a licensed electrician.

This gasket forms the watertight seal between the 4 in. lens and the light body on the SpaBrite fixture. A failed or compressed gasket allows water to enter the light housing, which can compromise the fixture and create a safety hazard. Replacing this gasket at each bulb service interval is standard practice to maintain a reliable seal.

Pentair SpaBrite / AquaLight SPABRITE Gasket for 4 in. dia. lens, off white

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 lens gasket every time you replace the bulb. Even if the gasket appears intact, a gasket that has been compressed under the lens ring for an extended period will not re-seal reliably when reinstalled. Replacing this low-cost gasket at every service keeps the housing dry and protects the light fixture from water damage. Pool lighting components operate in wet environments — always ensure power to the light circuit is off and locked out before opening the light housing, and have all work performed by a licensed electrician in compliance with NEC Article 680.
