This remarkably practical two-part gadget transforms a standard plastic bucket into a rugged, gasketed, resealable storage container that's both air-tight. Just snap the outer ring down onto your bucket. The threaded lid turns easily with molded-in grip bars. These lids are heavy duty for years and years of service. The ring has a polymer gasket where it sits against the lid of your bucket, and the threaded lid has another polymer gasket, giving the container an air-tight seal that excludes not only such freeloaders as mice and insects, but moisture too.
The Gamma Seal lid transforms an ordinary bucket into the ideal storage vault for an endless list of materials from grain and other foods to laundry products, pet food, tools, documents, silk ties, lawn and garden products, bait, seeds, oil, disaster supplies... and on and on. They also make lightweight, super-strong totes for camping gear. And did we mention that they're stackable? Our customers come back for more of these. (Make your life easier by ordering a few more the first time!)

“These lids keep my fresh grains fresh and free of bugs, dust, and other bad elements for well over a year. My grains smell as fresh and vibrant as the day I received them, and my baked goods are always flavorful and tasty. Fantastic pricing, impeccable service and delivery.”
– Devorah V., MA
All Gamma Lid plastics are food safe, including "heavy-metal-free" pigment in the colored lids, and all Gamma products are BPA-free. Gamma Seal lids do not include the bucket. Please note that color tint of plastic buckets can vary, so Gamma Lid colors may not perfectly match with the color of any given plastic buckets.
These 12" Gamma Seal lids fit 3-1/2 gallon or 5 gallon or 6 gallon buckets with standard top outside diameter of 11-3/4" to 12-1/8". If you want to use Gamma Seal Lids on buckets you already have, be sure your bucket tops have an outside diameter that falls within that range. (The buckets offered by Pleasant Hill Grain all have the proper top diameters to accept their respective size of Gamma Seal Lid.)
To install we recommend a large rubber mallet, or lay a 2x4 across the lid and strike with any heavy hammer. If a lid ring doesn't want to start on a bucket easily, submerging the ring or bucket rim (or both) in hot water will ease the connection.
Lids are sold in sets of three of each color. Colors include white, black, green, yellow, red, blue, and orange.
Note: If using oxygen absorbers in plastic buckets, you need to use standard hammer-on lids (not Gamma Lids). Gamma Lids are airtight, but are not designed to counteract the force of pressure that's created when all of the oxygen in the container is removed by oxygen absorbers. Once the standard lid is initially removed to start using the contents, a Gamma Lid can be used to re-seal the bucket against moisture, rodents and insects. A quality bucket and hammer-on gasketed lid will provide a fully adequate oxygen barrier for at least a couple years of storage. For even longer term oxygen-free storage, inside your buckets you can also use Mylar liner bags which, when heat-sealed shut around your food, will effectively block oxygen permeation for years and years.
