Captain O-RingCulligan Compatible OR-100 (OR100) O-Ring Replacement for Big Blue Filter Housing Buna-N ORing (3 Pack) [Also Compatible with Simpure DB10P/DB20P]

Will need these o-rings soon, they look good and should perform well

I loved the fact that they are O-Rings.It was also great that they were the correct size.And I was happy that they were much cheaper than my local hardware store.Seriously? These reviews are ridiculous. Wake up people!Insofar as this delivery (and one prior) they are good O-Rings and they are the correct size and they are much cheaper than my local store.But without knowledge about the person writing the review, does the review have ANY value whatsoever?

Buy some silicone grease with this also. I used to let Culligan come and change the filters until they jacked the price up. So now I order the filters, o-rings and grease through Amazon and do it myself. Simple and saves hundreds.

We can't tell you what we do with them, but they work fine.

I just changed my filters this morning and thought I'd use the old seals since they looked good. One of them slipped and got pinched between the case and the base. I'm glad I got the new seals since I needed it. It fit great and sealed up tight, no leaks!

Product is as described and worked perfectly. Received 3 in the package, which is great. I'm set for a while. Delivery was prompt.

Great value, exactly as described.

Appeared to be the one I needed.
