Product Description

Generic 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.

I have ordered a Pentair Lens Gasket Amerlite & SAM Light (791016) . What screw do I need to order to fasten the gasket to the lens?

A  Answered on 11/15/2018 by InyoPools Product Specialist Joe S.

Good day, there is not a screw that would fasten the gasket to the lens. There is only a screw that would attach the light housing to the niche, which would be 3525-03.

Hi, i have the larger 8" fixture in pool. It appears this will work. What about the smaller 4" ish gasket for the spa? do you have a PN for that? Thx

A  Answered on 5/22/2018 by InyoPools Product Specialist Hector F.

So if we base your question off of the Amerlite series pool light model then that would potentially reference the Spabrite/Aqualight spa light series. That gasket would be listed as key number 3 on the parts diagram that you can view here to confirm that this is indeed your spa light. If you cannot verify that then we would advise to look for the model label on the cone of the light or take a few pictures of it and email those to so we can identify it.

My existing light fixture is 120v 250 w since I am replacing gasket and bulb would be possible to change LED instead if yes what do I have to do Thanks

A  Answered on 4/30/2017 by InyoPools Product Specialist Stacey M.

Hello, You would have to make sure what type of light you have, the ones that you can switch over is if you have Hayward Astrolite SP058 Series, Pentair Amerlite 784 Series, Note: Not compatible with Swimquip Light Fixtures or Hayward SP0540 series.

Hi, I need a gasket for a 12 volts spa light that is about 20 years old with the inscription "WADE DESIGN" on the glass. The glass lens diameter is 3 3/4". The original gasket is grey and has these dimensions: *outside diameter is in between 3 3/4" and 3 7/8" * inside diameter is about 3 3/8" * measured difference between outside and inside diameter is 1/4" * thickness is about 3/8" I read somewhere that Gasket Lens Spx0590G Opt 3553-03 gasket might fit, but want to make sure.

A  Answered on 3/31/2017 by InyoPools Product Specialist Scott W.

It might fit but to be sure I need to know the model of your light fixture. If you can attach a picture of your light fixture so I can identify it, I will be able to find the correct lens gasket.

Can't read the type all I see is it's American Product. Will this gasket fit?

A  Answered on 6/5/2016 by InyoPools Product Specialist Patrick P.

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.

Does this gasket work with the fixture that takes the NA704 replacement bulb?

A  Answered on 7/26/2015 by InyoPools Product Specialist Hector F.

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.

when replacing pool light gasket. does the light housing go inside the gasket with lines

A  Answered on 7/1/2015 by InyoPools Product Specialist Hector F.

Actually the light lens goes inside the gasket gap.

?     Asked on 6/26/2012 by Guest

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

A  Answered on 6/26/2012 by InyoPools Product Specialist Patrick P.

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.

bulb was burned out and gasket deteriorated

Written on 4/19/2017 by Guest

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.

Were these instructions helpful?
