8-1/2" replacement lens gasket for the Pentair Amerlite and SAM lights. Replaces the OEM lens gasket 79101600.
The lens gasket provides a seal between the face ring and glass lens to prevent water from getting inside the fixture.
It is strongly recommended to replace the lens gasket when replacing a pool light bulb. Over time, use, heat, and chemicals will compress the gasket and can cause it to fail. A light bulb change is the perfect opportunity to replace this very important seal.
Frequently Bought with this Lens Gasket
My inground pool was installed with a 120V Amerlite standard incandescent light fixture. After ~ 3 years water started seeping into the fixture, so I replaced the bulb and got a new gasket. The one I got was the white-colored OEM gasket. It has since been leaking even more than before. I've lubricated it, made sure everything was snug and re-inserted it to no avail. Do I need a new light fixture, or did I just get the wrong gasket for this light? (there's also a standard black-colored gasket). H
I personally would try another gasket and would suggest the Extra Heavy Duty Guardian Gasket for the Pentair Amerilite If this does not work then the next step would be to replace the entire fixture with a new Complete Pentair Amerlite Fixture If you did end up going with the new fixture then you would have an extra Gasket which may not be a bad thing as these do need to be replaced periodically.
Does this gasket work with the fixture that takes the NA704 replacement bulb?
This gasket only works for the Pentair Amerilite and Sam light models but the bulb is used on multiple models. The specific light model would be needed to cross reference the correct gasket needed.
Can't read the type all I see is it's American Product. Will this gasket fit?
Can you send us a photo with a measuring tape in the photo, showing the width of the light and the depth of the light.
Hello,I am looking for lens gasket for American products co.k996044, will this gasket work? Also pentair seems to be compatible with American products,are they the same company?thanks for your time,Alan

I started by removing the pool light from the niche. Each required a standard #2 Phillips screwdriver. Once I unwound the tucked-in wire, I was able to place the light onto the gutter of the pool. Some of our lights had bolts with Philips heads - others used a 3/8" socket nut/bolt. Once I removed the clamp screw, the need for cleaning became evident. Some of our lights are quite old, and the corrosion on the housing is evident. I gently scraped/wiped this corrosion, some algae and filth off of the mating surface of the housing. Likewise for the glass. In both cases, some stuck-on remains of the old gasket required very gentle scraping with a straight-end razor blade. Once everything was clean (and dry!), I installed the new gasket and clamp. I tightened down the bolt firmly, then coiled up the wire and replaced the light into the underwater niche.

Since I was in the middle of emptying the pool due to chlorine lock, only using 3" chlorine tablets for past eight months, I decided to repair the pool light, water leaked into light shorting the circuit and causing GFCI to trip, did not replace gasket last time I replaced bulb, my bad. Before tackling the job find a few videos to watch to help visualize how to do it!
1. Emptied pool, only because I had to for another reason, there is no need to empty pool to repair the light, the cord should be long enough to put the light on the deck.
2.Turned off breaker to pool electrical and removed light to pool deck
3. Using a 3/8" wrench for bolt head and 7/16" wrench for nut removed retaining ring
4. Used flat blade screwdriver to loosen seal and separate lens gasket from light housing
5. Carefully unscrewed bulb, bulb had hole burned through at base
6. There was corrosion and rust in socket so poured CLR into socket and let soak for 15 minutes rinsed with water, towel dried and left it in the sun to dry for three days while I did tile repair
7. Inspected socket, then using electrical contact burnishing tool to remove oxidation on the bulb contact, installed new bulb, turned on breaker to electrical, turned on light for a few seconds to insure light worked
8. Removed old gasket from lens and cleaned lens
9. Installed new gasket on lens, the gasket is the same on front and back so just install it on the lens
10. Replaced badly misshapen retaining unitension wire, put light housing on the deck with the bulb facing up, put the lens with gasket on housing being sure to center it and make sure half moons on lens are pointed toward bottom of light, place face ring on gasket being sure to center it, make sure the retaining clips are evenly spaced around face ring, place the unitension wire on the clips with the bolt loops facing down, put the bolt into the loop pull loops together with channel locks install washer and nut. Tighten nut until loops touch
11. Install light into pool housing putting slot on bottom of light over the retainer at the bottom of the pool housing, push light flush with pool wall and install the single screw at the top.

Screwdriver, Nut Drivers, digital volt meter
As the original submerged light was 1/2 full of water, the problem was obvious. The gasket had failed sometime in the past.
I ordered a new lens gasket to complete the repair. I shut off all power to the light and VERIFIED power was off with my digital volt meter. I then proceeded with the repair by removing the stainless machine screw that holds the light into the fixture, then removed the light from the fixture, removed old gasket, and replaced with the new 79101600 gasket.
All this was done while sitting on "noodle" floats in the water! No need to drain any water! However, at this point, I decided to go ahead and get a new color- changing LED pool light from INYO Pools (which I will detail the install in another post). No sense "putting perfume on a pig" as they say!

watched inyo video for replacing bulb and gasket. I ordered a new 100w, 12v bulb and gasket from inyo.
my lamp was exactly as shown in the video. I followed the step by step instructions and the job was complete in
less than an hour.

Seems like a quality product. That said, a year later, several fixtures have begun leaking again. I'm pretty sure it's not primarily the fault of the gasket though. Several of my fixtures are older and have a rougher mating surface (due to stuck-on contamination/corrosion). I've just re-seated several, making a more aggressive attempt at cleaning the metal. We'll see if that holds better. These lights are difficult to work on, in my limited experience. I'd still recommend the product, as my suspicion is that the higher-priced OEM model would perform no better. The price is great.
