I don't know if this is true but Culligan sells an OR-34A set with two sizes one of which you will not need. This product appears to be the proper size for the "A" housing as advertised, 4 1/8" diameter measured by me, and looks exactly like the original o-ring. It is the best value I have seen. I ordered four and was charged the same shipping rate as for one and they came in a single zip lock bag. Nice to have spares in case you pinch one with a misaligned installation.The o-ring appears to belong on the step above a circular groove in the housing that is smaller than the o-ring. My first attempt to screw on the housing resulted in the o-ring falling down into this groove causing leaks and possibly being damaged. I urge you to use a silicone grease like Dow Corning MOLYKOTE for several reasons: it will hold the o-ring on the step as you install the housing, it provides lubrication, it slows down leaks. ### ⭐⭐⭐⭐⭐ Works as expected *by T***R on Reviewed in the United States on September 16, 2012* These O-Rings work perfectly in my water filter.The fit is perfect. Not too large, not too small.THe only thing i can recommend HIGHLY when installing these... use vasoline.Coat the entire O-RING in vasoline and then put it in and then put on the top. I also put vasoline on the threads of the cap for the water filter too.The vasoline on the o-ring holds it in place better and it helps make a better seal.With vasoline on the threads of the filter cap, not only does the cap go on more easily and come off more easily, but it has a great seal AND... i don't have to put the cap on as tightly. ### ⭐⭐⭐⭐ Does the trick! *by B***S on Reviewed in the United States on August 29, 2013* I have two whole house filters, and have had them installed for a number of years. Never changed the original rings till I got these in. Now the first set were still good as far as I know. I never had a problem with them, but thought it might be a good idea to go ahead and change them.The filters I have are the Culligan PF 160's( I think), and these fit fine. I installed them, and the install went on without a hitch. Afterward no leaks, no problem o! Now, these should last for years, and since there were two in the package, and I got two packages.....I shouldn't have to order more in my life time! Sorry Culligan!BTW....I LIKE this item. I don't LOVE IT.....I love my wife. :) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/184315874-culliganor-34-o-ring-of-4-125-inch-diameter-2](https://www.desertcart.us/products/184315874-culliganor-34-o-ring-of-4-125-inch-diameter-2) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-13*
