Pentair 350013 Lid O-Ring Replacement Pool and Spa Pump

Why did you pick this product vs others?:Seemed to match OEM number and right size.

Works and fits great

I've seen a couple of writeups attesting that this was "too thick", did not come in genuine Pentair packaging and therefore was not OEM, etc. However, I ordered this for my Pentair variable speed pump based on the part number and it arrived in vacuum sealed Pentair OEM packaging.When I opened the package I simply cleaned the ring with a paper towel since it had some packaging/manufacturing "residue", then I applied a liberal amount of Hayward's Jack's Multilube (good stuff, although a bit expensive), and I got a nice seal on my pump.A couple of tips:- Make sure you thoroughly clean the pump housing and the area of the pump itself where the O-ring is going to make contact. I just use a toothbrush, water, and paper towels for this task.- Use a disposable glove to hold the ring and put the lube on it. You don't want any of the lube on your skin or clothing because it's hard to take off.- VERY STRONGLY suggest you buy and install a Hayward W530 Large Capacity Leaf Canister in your system:(https://smile.amazon.com/gp/product/B001E2D62W/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1)-- This will make cleaning out the leaf canister on your pump a thing of the past, and will be easier to clean out than having to struggle with opening the leaf canister built into your pump-- Will do a better job filtering out leaves, trash, and other things out of your pump which will prolong the life of your pool pump since it has a finer filter mesh than the one built into the pump-- Will save you time and money (at least in my case, it keeps the occasional mouse that falls into the pool out of the pool lines preventing clogs that require a professional to blow out of the line)

Genuine Pentair part.

Works well and seals well in the pump

I just had leaking problems with my Pentair 4-cartridge pool filter and my pool guy suggested I replace the o-ring. I also bought silicon grease from Lowes. Its now better than the previous professional install and no leaks at all after 6 months. This was much cheaper than the local pool supply shop and the same or better quality.I did try initially installing this without silicon grease and it leaked badly. I would only install this with fresh grease every time from now on.

I have a pool and hot tub that sit 4-10 feet below my pumps and filters. Suction is a big deal. I had old tops and old rings, I did not realize how bad they were impacting the suction getting water from the pool up to the pumps...ugh. I waited too long, but now it is amazing....

Inexpensive way to keep your pool pump running smoothly. I replace mine every 2 years
