Red Sea Reefer o-ring size

Hi everyone!

I’m hoping you can help me with a plumbing question! I moved my Red Sea Reefer 170 to a new apartment last weekend. When I set it back up, I discovered that the return and drain lines to the sump are leaking. I believe the o-rings need to be replaced as they are looking kind of worn. I’ve tried a few different sizes but haven’t found one that fits yet. Does anyone know what size o-ring will fit a Red Sea Reefer? Thank you so much for your help!!

Not sure the sizes but you can get an Oring kit from aquariumpart.com cheap shipping too
