Swimming Pool Machine Knob Cover Rings 8 Pack

I like these because they're so much cheaper than when you get them in the store but they work! They are a bit smaller than the Hayward ones we purchased previously (at $45 apiece!!!!), so it takes some work to replace them properly. My husband is a builder (he built our pool) so he has no issues with them, but if you're not savvy with pool equipment this product could pose some difficulty. But for us it works just fine.

These fit perfectly and stopped the leak from the original o-ring getting pinched. Great price and now I have 7 more 0-rings in reserve when this one goes out. All for less than one from the pool supply store. I work on cars and other equipment so I'm no stranger to o-rings of all sizes. These feel as good as any other and even if they don't last as long it's still a great deal and I can just swap it without having to source one. I like having parts like this on hand so I don't have to drive to the store or wait for shipping.

Ordered to use on my Hayward chlorinator and it was a perfect fit. Price was excellent as well.

Excelent quality o rings, takes care of leaks and they fit really well. No complaints.

Bought these AR-PRO 8-Pack Replacement O-Rings for my Hayward chlorinator. I was down to my last ring and ordered this pack, especially at the price which is nowhere near what you pay for name brand o-rings. They work great! It fit snug on the inner lid of my chlorinator with no leaks whatsoever. Anyone with a chlorine pool knows that replacing rings is a part of maintenance. With 8 rings, you won't have to worry about running out of them any time soon. Two thumbs up from me!

Best rave bracelets I've ever had!

This o rings fits perfectly in the hayward chlorinator cl220, great product.

Good quality and a good item to have for a spare. Well-made and good fit.

Joints parfaits pour la cellule au sel de Hayward. Livraison rapide et bon prix.

Perfect fit for my chlorinator. Looks different than the original but works very well

Wrong size

Fit like a glove on my chlorinator for a fraction of the price and no more leaks.

I purchased and installed a year ago - worked great. Lasted all season. I'm writing this review now because the o-ring just failed and I went online to order one and realized I had bought an 8-pack. Glad I did! Found them and installed a new one. Problem fixed.
