Hayward ECX1105 Replacement Pool Filter Diaphragm Gasket (EC65/EC65A/EC75/EC75A)

This is a direct replacement for a Hayward gasket but came from Leslie’s Pool. I replaced this gasket 2 years ago ordered fromAmazon and was an Appliafit? The quality did not appear very good and was a poor fit but I installed it anyway. It was badly deteriorated and was leaking when I removed it ( see photo). The new gasket appears to be a better quality, fit well and no leaks. Only been in service two days but I hope it lasts longer than the previous one. If it does last it will be good value for the price.

Definitely not a Hayward OEM replacement. My filter was 17 years old and the gasket was showing signs of wear. I purchased this "OEM replacement filter" . The picture shows what it looked like after two years in upstate NY(actual operation ~ 10 months) . It may be cheaper than at the pool store, but the pool store Hayward product will last 17 years, this won't last 2. Easy decision

Removed old gasket and installed new gasket everything went easy working great.

I purchased this item a year ago to replace my 20 year old, yes, 20 year old Hayward gasket. It appeared to work fine last summer, however, this spring when reinstalling the diaphragm, the fit seemed to be extremely loose. None the less, I expected that the top of the unit would hold it in place just fine once the bolts were installed. This was a serious mistake on my part.I started the filter after the installation was completed, however, a minor drip began so I did a bit more checking on the lid bolts to ensure all was well. It dripped a few drops but I wanted to clean my pool, so I let it go until I was able to complete the task and then the plan was to remove the top of the filter..again. Another bad idea on my part. Once the cleaning was done, I checked the filter and it was no longer dripping, so I let it continue to run.I proceeded to mow and trim my yard, a two hour job. Upon returning to the filter, the timer had shut the pump down. However, upon closer inspection, it was obvious that the prime had been lost. This was troubling to me, so I immediately removed the pump lid and all 300 bolts.. well, it seems like 300 bolts....What had occurred? The entire tube sheet was partially sucked down into the bottom of the filter body. This must have occurred when the timer turned the pump off, so pressure against the tube sheet was no longer holding it in place. The gasket had literally transformed into a ring of mush. The pump lid could not retain the beaded ring in the filter body groove. This fake junk has cost me time and material to deal with, not to mention the initial cost of a counterfeit part.Beware! You will NOT receive what you THINK you are receiving.

Needed a replacement diaphragm gasket for my filter, this one is advertised as Hayward (Manufacturer) but arrived in Leslie's pool packaging. It is obviously an aftermarket part not genuine Hayward. That being said it did fit properly in my EC65 filter and is working, the only concerns are how it will hold up over time

This is a great product for a great price, really easy to install.

The O rings in the pack are a little smaller in cross section so they fit in the oring slot better than the other ones I have used. None of the other orings I have used, last very long. They expand in cross section and diamater to overfill the space available and prevent the lid from properly screwing on.

Fit perfectly
