Review: Genuine Pentair OEM O-Ring in Pentair packaging; easy to install - 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.desertcart.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) ## Features - Lid o-ring replacement - Fits Pentair IntelliFlo VF, VS 3050, VS-SVRS and WhisperFlo, Challenger, Pinnacle inground pool/spa pumps - Also fits Pentair EQ-Series commercial and WaterFall pool/spa pumps - Measures 6-1/4-inch length by 1/4-inch height by 6-1/4-inch width ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001F5HU16 | | Best Sellers Rank | #150,699 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #4,345 in Pool & Spa Replacement Parts | | Brand | Pentair | | Brand Name | Pentair | | Color | black | | Customer Reviews | 4.6 out of 5 stars 1,069 Reviews | | Global Trade Identification Number | 00788379657710 | | Item Diameter | 6.38 Inches | | Item Weight | 27.22 g | | Manufacturer | Pentair - Distribution | | Material | Rubber | | Material Type | Rubber | | Model | 350013Z | | Nominal Outside Diameter | 6.25 Inches | | Part Number | 350013 | | Set Name | single | | UPC | 788379657710 852673930012 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Pentair - **Color:** black - **Item Diameter:** 6.38 Inches - **Material:** Rubber - **Nominal Outside Diameter:** 6.25 Inches ## Images ![Pentair 350013 Lid O-Ring, Challenger (All), WFE (After 11/98) - Image 1](https://m.media-amazon.com/images/I/51gLXc4gzWL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good fit *by S***L on July 12, 2025* Why did you pick this product vs others?: Seemed to match OEM number and right size. ### ⭐⭐⭐⭐⭐ Genuine Pentair OEM O-Ring in Pentair packaging; easy to install *by J***Z on February 22, 2022* 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.
