Reefocto calreact 220

Does anyone know the size of the ORings in the ReefOcto Cal React 220 ?

Just bought a second hand unit and it seems to be sucking in air wanted to replace them to rule of seal failure

Ideally I will replace them all understand the one in the ph probe spot is also a serial lead offender

Thanks so much for any help

Someone else probably has the size memorized, but that’s not me.

My lifetime experience with o-rings has taught me to know that in the industrial centers there are specialty hardware stores that have rooms with cabinets & drawers that are full of different sizes of o-rings, different rubber types etc. I know where these stores are located and they sell to walk in customers, or at least they did before COVID?

I grew up using an ap called “The Yellow Pages” which got swallowed up by Google that subsequently became a merchandising tool that prevents people from finding who is selling nuts, bolts, and O-rings in specific areas.

I live in San Diego county, where are you located? These shops have tools to figure out what size oring you have, and they may be able to help determine what material it’s made from to?

I replaced my orings by visiting the local store and they were very helpful to solve my similar problem.

I do think that they were a metric sized item, but I’m not really sure. HTH!

Post your location and maybe some other reefers near you can put you in touch with a local hardware store?


I had to replace my circulation pump also-

Thank you for your detailed reply

I am in Sydney Australia so metric starts to get a little tricky
