Product details
The Pentair 78880200 is the lens seal for the Aqualumin light assembly. It is the genuine Pentair part: a white rubber gasket with an L shaped cross section rather than a plain round o-ring.
Dimensions
Outside diameter 7-1/2 inches, inside diameter 6-3/4 inches. The section is stepped, 1/4 inch thick on the inside and 1/8 inch on the outside, which is what lets it sit into the lens groove and seal against the housing face.
Fitting it
Because the section is L shaped, the seal only goes in one way round. Look at how the old one is seated before you lift it out. Seals go hard and take a permanent flat spot after years of lamp heat, so a light that has been opened is worth resealing rather than reusing the old gasket.

Questions and answers
What people ask about this product, answered by our pool techs.
What are the dimensions?
7-1/2 inch outside diameter, 6-3/4 inch inside diameter. The cross section is L shaped and steps from 1/4 inch thick on the inside to 1/8 inch on the outside.
Is this a plain o-ring?
No. It is a stepped gasket with an L shaped cross section, so it has a defined orientation. Note which way the old one sat before you pull it out.
Which light does it fit?
The Pentair Aqualumin light assembly. It is the genuine Pentair part, number 78880200.
Should I replace it when I change the bulb?
It is the sensible time to do it. The seal is what keeps water out of the fixture, it hardens with heat and age, and it costs far less than the light it protects.
