Sanke fermenter gasket ideas

[Komocabo]

I cut the top off of my sanke fermenter because I want to use a plexiglass lid (easier to clean, can visually see fermentation, etc).

The plan is to secure the plexiglass (lid) with some clamps. I have a handle on all if this, and will update as I go.

The question I have is how do I make (or buy?) A gasket that is about 9.5" ID. I saw a video on YouTube where a guy put silicone into a tube, let it cure, Then pulled/cut it out and connected the two ends... gasket made! I am going to give it the college try, but I'm not very hopeful.

Any one else make a gasket for this purpose, or have any ideas what I can or should use?

Here's the fermenter as it is today. Cheers.

It doesn't have to be fancy...

What about something like this?

You could slice some silicone tubing ling ways and slip it over lip edge of tray, to act as soft gasket. Just put it face down on keg. No clamps necessary.

Ok, picked up a 1'x4' sheet of food grade rubber (can't remember what it's called) from Pacific Rubber in Eugene, OR. It was pricey ($26 for that!) BUT I can make at least 4 gaskets out of what. Picked up. Its 1/8" thick. Going to cut it to match the lid, grab some fasteners tonight and should have a finished product tonight! Will post once done, as well as parts I used. Its coming together nicely

Here's what I did tonight. Haven't taken off the plastic layer... should look as clear as glass! I'm feeling good about the progress

Edit: The "gasket" is White FDA Nitrile

I worked out the seal... I'll take a shot of it, in action, tonight. Basically, I took two 1"x12" bars and they fit PERFECTLY under the rim of the keg to tightly secure the lid and gasket. After seeing a few ideas online I was going to make something too complex... I have to admit, this part was dumb luck. Had I cut the hole any larger, or smaller, this would not have worked.

Brewed an IPA on Sunday so it's in The fermentation chamber happily at 18°C.

And here it is in action!

Neat!

You know, you could just put some weight on it, and let ol' gravity give you a hand.........
