R172009 Chlorine Resistant VITON O-Ring 2 Pack + Lubricant for Pentair Rainbow Chlorinator 300 & 320 Lid

Fit and worked perfectly the first time. No more leaking and no more cranking the lid down.

The product (O-Ring) was exactly as described and slipped exactly into place and immediately sealed up my Polaris 320 Chlorinator. I still can’t believe Polaris is selling their units with junk O-Rings. I talked to a pro pool guy and he said they’ve known for years… And the OEM O-Rings barely last a season! Luckily these guys are here to save the day! No more $10 single season O-Rings for me! Buy these with confidence.

This o-ring was a drop-in fit for the stock black rubber o-ring in the cap of my Pentair Rainbow 320 chlorinator chemical feeder. There were no leaks.My original black rubber 0-ring had lasted from 2018 - 2024 but I made the mistake of removing it from the cap to inspect it. It had swelled to 150% of its original size, but more importantly, was suddenly an inch too long to go back into the cap! The years or chemical exposure to chlorine and Rainbow Silicone grease had swelled it apparently. If your old rubber o-ring has been in for a while, you may well need one of these o-rings if you remove the old one from the cap.The Pentair rubber o-rings are $14 each, so these Viton rings are a much better value. The Viton material should last much longer as well. I have only run this Viton o-ring for a few weeks and will check its condition at the end of the 2024 swimming season.

Fits perfectly and includes enough lubricant for the two rings in the package. Better quality than the competitors plain rubber rings and I expect it to last longer because it is chlorine resistant.

Fast delivery. The product was new and as advertised. Installation was simple and resolved the water leak

The o ring rubber is 3/16" diameter while the old one was 1/4". I couldn't find 1/4" and verified this is the correct part number for my brand which is Super Pro Model spchr. The new ring fit but leaked initially. I smeared on the grease that came with it and put it back and no more leak. However, the original 1/4" O ring lasted almost 4 yrs, no grease and opened/closed chlorinator almost every week. Hasn't been in use long enough to rate it's durability. Guessing I'll have to replace after one season. At least it's a two pack.

These ring gaskets fit perfectly and seal the chlorine dispenser cap as described. I am excited to have these last longer than the previous ring which simply disintegrated.

Really like the thorough customer service. Product worked great and was shipped fast. Would definitely do business again

Better than I expected. Good item.😍😍😍 So far this is showing results! I don't usually want to rate a product so highly but in this case I've found this pest repeller to be extremely effective. A few months back I'd gone on vacation and came back to find some mice had quite the party in my basement while I was away, and immediately I searched for something that wouldn't have me have to clean up dead mice. Installed these devices and setup was super simple and I also set out some baited glue traps to see what would be more effective. Went away again on a 4-day vaca recently and wasn't looking forward to picking up the mice I just knew would be stuck to the glue traps. To my surprise, there were no mice at all on the traps! Easy setup!! Easy instructions!! Sleek design!!
