    Perfect O-Ring for my Pool Filter (it replaced P6119 O-Ring)
  

*by L***R on Reviewed in the United States on June 13, 2024*

Instead of buying a  2 pack of P6119 O-Rings for my pool filter, I bought this pack of 10 for about half the price. These work perfectly. No fuss at all. It went on easily, and seals perfectly,.I'm very happy to get 10 O-Rings for a lot cheaper than the pack of 2 OEM P6119 O-Rings.Highly recommended.
