Southeastern Accessory Pool Spa Multiport Valve 1.5" Diverter Spider Gasket Replacement for Pentair(R)* 271104 G-416 | 5-1/4" Outside Diameter, 3/4" Inside Diameter Center Hole, 1/4" Gasket Thickness

Seems the gaskets on line pretty much have the same dimensions. If you know what you have then you can save quite a bit of $ getting another model

Check out my photos. This valve gasket fit great. My previous gasket lasted about 10 years. I dont use the valve anymore. Insteaed, when I need to clean my DE filter, I disassemble the filter. My pool guy was trying to be helpful last week and he ended up damaging the gasket. There are at least two different spider gaskets, this smaller 5.35" for 1.5" valves and a larger one for 2" valves.I put the flat side down, ribbed side up like the previous gasket and then applied plenty of silicone grease. I have no leaks now.When I added this spider gasket to my cart, I was advised to also buy a 4.6-inch O-ring. Since I didn't know the diameter of this spider gasket, I ordered the O-ring. From my photo, you can see that the O-ring is bigger than the spider gasket. I re-used my old gasket. Maybe next time I need a spider gasket, I'll come back to this review and then try to find the correct 5.75" O-ring. The valve should be about 50 years old by then. Ha.

The spider gasket fit perfectly in my Praher multi port valve and it was considerably less cost than the local pool store. Returned my 15 year old multi-port valve to like-new condition. Removing the old, decomposing spider gasket was not easy. The rubber becomes sticky when it gets old and it was a battle to remove it, as well as the old glue without scratching and damaging the channels that are needed to hold the new gasket in place.

Extras for future need. I couldn't pass up the opportunity to purchase these at such a low price. I was pleased to see that the quality was more than adequate.

I've had my pool for 17 years, and have had to replace the spider gasket twice before. In the fall of 2019, when I closed my pool, I noticed that the gasket needed to be replaced again. I bought this spider gasket. It was the right size, and easy to install. I opened my pool 3 weeks ago, and have been having problems. When I checked the spider gasket, it was all swelled up and deformed. I would not recommend this product.

This was the cheapest valve gasket on amazon. It Came in just a couple days.

Quick easy thank you

I figured "who could screw up a rubber gasket" so I picked this cheap replacement part. Garbage. Too tall, a very hard rubber and clearly not a fit for an original 271104. I replaced it with a Pentair 271104 which fit and worked perfectly (and it only cost $13). False economy to buy junk parts, I feel dumb for falling for it.
