Overflow box leaking

[Pdfcrazy]

So....new to forum, not to aquarium keeping. Have an amiracle overflow box flowing to a custom twenty gallon long refugium. The white bulkhead in the overflow box has an O-ring inside the acrylic, and one outside. The O-rings have degraded to the point they were splitting and wouldnt seal. We have tried all local hardware stores (lowes, home depot, etc) and cannot find ones that are thick enough. Anyone know of any good source? As far as I know, amiracle is out of bussiness. Not an emergency, but getting alot of dripage, and saltcreep down the flex hose and need to get this fixed soon.

Have you tried our good friend "Google"? I think you'll be able to find something close to the size you're looking for form one of the array of places selling o-rings. If not, you could always try to make a flat washer set out of a piece of silicone sheet picked up from Amazon or someplace. I'm just not too good at using scissors for such, and you really don't want to see my X-acto knife work on silicone. Functional, but not pretty.

In a last ditch effort, break out the tube of aquarium sealant and run a bead inside both sides of bulkhead (replacing the o-rings), seat, tighten, and let it cure for 24 hours. You'd have to keep your sump and aquarium circulating separately while it cures, but as it's not really a pressure seal, you shouldn't have too much of a problem with it leaking from that point forward. If you ever tighten or loosen the that connection, however, it will break that seal.

Hope that helps a bit.
Cheers,
Ray

try a auto parts store....my local napa has a drawer just full of different sized O rings...from quarter inch to 2 inches

Will one of these work?

Found some flat rubber washers in the plumbing section, intended for sink faucet repair, but they should work.
