GAMMA2 Gamma Seal Lid- Pet Food Storage Container Lids - Fits 3.5, 5, 6, 7 Gallon Buckets, White, 6-Count, Made in USA

The Gamma Seal Lid is a food grade plastic lid that can fit any 3.5 or 5 gallon bucket, with an OD of about 12-1/2" for the ring that snaps onto the bucket, and an OD of about 11-5/8" for the lid itself. The lid comes in two pieces, and the seal snaps onto the bucket and cannot be easily removed. The lids can be stacked but not as tightly. Some reviewers have reported that the lids leaked, but this could be fixed with Teflon tape or replacing the inner seal. Despite being expensive for plastic, the lids are tight fitting and can be used for long term food storage.
