I LOVE the Gamma Seal lid.
You can place it on any 12" diameter bucket.
It makes the bucket airtight and leak proof.
There are 2 pieces to the gamma seal lid.--The "o ring" and the lid.
There are 5 colors to choose from: White, Red, Blue, Yellow and Black
I bought mine at www.beprepared.com for less than $10.
WHY and HOW I USE THE GAMMA SEAL LID:
WHY?
The gamma Seal lid saves me a lot of money.
HOW?
I have my year supply of basics stored away in cans from the cannery.
I don't open my cans of oats, sugar, flour, and wheat. (These are foods I use all the time.)
Instead, I have 4 food-grade buckets with gamma seal lids. I fill them with bulk bags that I bought from the cannery. The bulk bags of food are really inexpensive!!
Here is the "o ring". It snaps on and stays on the top of edge of the bucket all the time.
As you can see, I am almost out of wheat. Time to refill!
Here is the lid. You can see the white rubber seal.
I just refilled my bucket with (1) 25 lb. bag of wheat.
The lid is so easy to twist on.
Here is the top of the lid. The bucket is now sealed.
