Hands On: Gamma Seal Lids for Grain Storage

Gamma Seal Lids, used in conjunction with standard buckets are a very popular option for grain storage.  I recently picked up one to give a try.

Close up on the top portion of the label.  This fits 3.5 to 7 gallon buckets.  A lot of specifications list 5 gallon as the top end.  Other listed features: Heavy Duty, Easy to open and close and unlimited uses.
Close up of bottom left portion of the label includes assembly instructions and Made in the USA label.

I found that the lid is easy to screw on and off.

High quality, gasketed lids do exist for 5 gallon buckets.  I haven’t seen any that claim to be airtight, but my guess is that they are airtight or near airtight.  The problem with these lids is… they are usually difficult to remove.  The revolutionary thing about Gamma seal lids is that the ring stays installed on the bucket.  That ring is used in conjunction with an easy to remove spin off lid that features airtight seals.

This is a great option for grain storage.  I found the lid to be well built and easy to use.

A 5 gallon bucket will hold right around 25 lbs of grain.  Two buckets and two gamma seal lids gets you a full 50 lb sack of grain.

I ordered this Amazon.  The product description says “Assorted Colors”.  I take that to mean they are going to send you whatever color they’d like.  The product picture shows a black lid, I received a white lid.


Another source for these is Home Depot.  It’s worth noting that the product description does not specifically say these are Gamma Seal brand, but… the Model number is listed as 5GAMMA6 and if you zoom into the picture it clearly says Gamma Seal Lid.

    I use one of these on my primary fermenter. I’ve done about 4 brews with it. I drilled a hole in the exact middle of the lid for the airlock and it works great. Leaves just enough clearance for the handle and my knuckles to clear it while transporting it.

    The ring around the top CAN be a great place for bacteria to grow so after removing the beer I spray hot water along the bottom of the ring with the vegetable sprayer on my sink. Then I fill the bucket all the way to the top with super hot water and PBW, put the lid on and let it sit overnight. The next day I drain thoroughly rinse, set upside down to dry and then put it away with the lid on tight. So far, I have never had an infection. Even on big beers when the krausen reached the lid, they turned out fine.

    Has anyone tried these lids on a fermenter yet? My current lids are getting old and seem to leak a little.

    Could anyone comment on using these as a primary bucket lid by drilling a grommet hole for an airlock? Do they seal tight enough for that? Seems like twisting it off would be more ideal than popping off the regular lids which could shake up trub? Make sense?

      I believe that they are tight enough for this to work. My concern would be cleaning and sanitizing. Awful lot of space in nooks and crannies that would be hard to clean and sanitize. If you were planning to completely remove the outer ring every time, I think it would be fine.

    Picked up two last week from Home Depot. The lids were $6 each and the buckets were $2 and change, not a bad option at all.
