Alternate Part #'s 3011215, 3011222, 791016, 79101600Z, 79101601Z, 7910161, 791016N, AMP3011222, O-170, O170
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
lens gasket 79-101-600-0-170 . this gasket has a smooth side and the other side has two ribs. Which side of the gasket face is place on the light cone. Smooth or ribbed
Hi Mark, the smooth side of the lens gasket is to be on the outside exposed and the ribs are to be wrapped around the outside of the lens itself. The lens rim essentially is fitted inside of the gasket.
Would like to replace bulb with led and gasket. Please advise which bulb and gasket are appropriate. Thank you.
Hi Quen, this would be the correct lens gasket and you would also need the J & J Colorsplash LED light bulb. Here is a guide that we put together for upgrading your pool light to an LED color light changing one that also may assist.
Hi, need help to identify proper replacement lens gasket. Label on housing unit totally corroded by algae. Used in an American Products niche that says use with BC-300, BC-400, or BC 500. But the OD and interior diameters of the gasket for those models seem larger than mine (est. 7 3/4 OD and 6 7/8 int diameters). Hopefully, the attached photos will help. Might it be a hatteras or hayward light instead of American Products? It was installed in 1991. thanks much.
Hello, can you confirm this seal fits the 'pentair 784 788 789 light seal'?
Hi Christian, yes this lens gasket fits your Pentair 784xxx Amerlite pool light series.

Hello, would this gasket fit? thank you.
I need to replace the gasket and would like to replace the bulb with and LED light. Can you please reccomend both to buy ?
Can't find a name on my light but the lens is 7 1/2 inches wide. Need a gasket
Hello, we would just need to know the specific pool light model to confirm for you. The model should be located on the rear of the fixture on a label. If not legible, could you send us a few photos? One of the entire light fixture, the lens itself, and the dimensions of it? To supply photos simply click the reply link below and upload your photos or quickest on using our live online chat feature. Once we get those photos we can make the proper recommendation.
My pool light shorted out last year. I think water got inside. I'm looking for a replacement bulb and gasket or the pictured fixture. Thank-you.
Unfortunately, I cannot use any information on this label, it all regards UL listings and dates approved. Please provide an image of the front of the fixture showing the lens with a tape measure across the lens and faceplate. We will also require the voltage and watts needed for the bulb. Please test the fixture to verify it did not short out the entire fixture before ordering the bulb and gasket.
I have an older model light cover, made by american products co , with #3915 embedded in the glass. The final dimensions of the gasket "on the lens' is 8-3/4 inches outside diameter, 7-5/8 inches inside diameter with 1/2 inch on each side, and 3/4 inches front to back. which gasket should I order? The bulb is 300 watts, 120 volts, screw in. Please recommend the bulb , gasket, and type lubricant or sealer to use.... Thanks
Hi, Richard. This is the correct lens gasket based on the info provided.
7.5" glass lens. Gasket looks loose and about 8" diameter. Can you please recommend a proper gasket?
I have an American products pilot light 7892xx, 7842xx
300 Watts, 120 volts, bulb R-40
Is this the correct gasket?
Or can you provide the correct gasket P/N or Model number.
I took my fixture apart because it had leaked a little over the winter. Cleaned it up and reassembling. Gasket looks good. Would a little 100% silicone caulking help around the lens and gasket?
We would not recommend using any silicone on these lens gaskets as that is not manufacture assembled that way.
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?
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.
need a gasket for a pool light fixture. dont know the model number. it is 25 years old. . the existing gasket is grey and is smaller , about 6.5 inch in dia. what should i buy??
Hi, Raj. Please provide pictures of your fixture so that we can try to identify and locate the correct gasket your fixture.
disassemble an aqua-lumina2 light to change the bulb.
Hi. Instructions are available in the AquaLumin II - Nicheless Light Operating Procedures Manual pages 14-15.
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
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 email@example.com so we can identify it.
Hello, could not get much info on this but this is what I got off the bulb housing:
7885xx 7845xx 7895XX
500 watt 120 volts bulb type R-40
Will this gasket fit my pool light housing / lens ?
Yes the Pentair Lens Gasket Amerlite & SAM Light (791016) would be the replacement gasket for your light housing.
Hi, the existing fixture is a Purex No E.905830... also says Model PLH-100-5 and Model PLH - 100-3. on the original mfg decal... Just trying to confirm which replacement gasket will work here.. thanks
Will this gasket fit my light. The model # is R 400BCL. Also I need a light bulb for the same fixture. The fixture indicates it is rated for a 400W bulb,120V. The fixture says bulb type: R-40. Pease tell me what bulb is designed for this fixture. Thank you.
Jim, The model number you provided does not show in my system. Can you please attach a photo of the label on your light fixture?
I have an inground installed in 1999, the light is an Aqua Lumin II. In the direction book it calls for a lens gasket with a part # of 788802 is this still available ? DO you stockit? Thanks for the info.
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
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.
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.
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
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.
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.
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.

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.
