Product details

The Pentair 79108500Z is the 4 inch rubber lens gasket for SpaBrite and AquaLight pool and spa lights. It is the genuine Pentair part.

What it seals

The gasket sits between the lens and the light housing. When the lens ring is tightened down, the rubber compresses and closes the joint, and that seal is the only thing keeping pool water out of the fixture.

Replace it every time you open the light

Rubber that has been clamped in place for a few seasons takes a permanent set and no longer springs back. It looks fine and it is not. Refitting an old gasket after a relamp is the single most common way a light ends up full of water, so put a new one in whenever the lens comes off.

What is included

The gasket only. The lens itself, the color lens kits and the fixture hardware are separate items.

Questions and answers

What people ask about this product, answered by our pool techs.

Which lights does this gasket fit?
Pentair SpaBrite and AquaLight pool and spa lights, the models that use the 4 inch lens.
Do I have to replace the gasket when I change a bulb?
Yes, replace it. Once a rubber gasket has been compressed in a fixture for years it takes a permanent set, and reusing it is the most common reason a relamped light floods.
Is it a genuine Pentair part?
Yes, Pentair part number 79108500Z.
Does the lens come with it?
No. This is the gasket only. The lens and the color lens kits are separate parts.
