I'm going to try to pick up a tube at Graingers on Monday and see what the tube says. It won't go to waste with the tinkering I do on aquariums.
Now where to get a food grade washer? Anyone have any suggestions?
I simply used a rubber washer from Ace . Not food grade but since it is such a small amount of rubber and not getting over 170 degrees I think it is safe enough .
If you want food grade seal then how about just putting some food grade silicone on a large washer ? If you want it to be removable then put a piece of plastic wrap over it and loosely tighten it down so the silicone will take the shape of the bucket or pot and wait for it to fully cure and then remove the plastic wrap . Now you have a food grade rubber washer .
you can get that food grade silicone at Graingers I think .
