Gamma Seal Lids – How To Install And Use Them

Gamma Seal Lids

Gamma Seal Lids (UPDATED) are specially designed to fit the top of a typical 5 gallon plastic bucket. Actually they will fit most buckets between 3.5 to 7.0 gallon due to a standard diameter.

Once installed, Gamma seal lids enable easy-on, easy-off because they simply screw-on and screw-off (spin).

Gamma seal lids convert 5 gallon plastic buckets into airtight storage containers with easy access – of which the benefits and uses are numerous.

Note: When I say “airtight”, it’s not the same as using a sealed Mylar bag with oxygen absorbers inside. However it still is quite effective. And the convenience factor is great!

Are Gamma Seal Lids Worth It?

Are they worth the money? Yes, I believe so…

In my opinion there are uses where it’s so convenient that it is worth the money (see example list below).

If you seal a bucket with the standard snap-on lid, it becomes very difficult to remove and is certainly NOT convenient for accessing its contents from time to time.

Tip: For standard lids, you need a special tool (bucket lid wrench / pail opener)

How To Install Gamma Seal Lid

The outer ring “snaps” to the top of the bucket with the help of a rubber mallet.

First remove the inner threaded lid from the ring.

Place the bucket on a solid surface and strike the ring hard enough to seat it.

Work your way around the ring until it all ‘snaps’ in place.

Then, simply spin on the detachable lid.

Tip: Before installing the snap-on ring, be sure there’s a gasket (O-ring) seated inside. This is what provides the main bucket-to-lid air-tight seal. Also be sure there’s an O-ring around the perimeter of the spin on/off lid. This provides the air-tight seal of the removable lid.

The Many Uses For A Gamma Seal Lid

Dry pet food storage
‘Working’ inventory storage of dry foods (rice, wheat, etc..)
Emergency supplies
Camping and Fishing gear
Bulk Laundry Detergents (larger sizes save you money)
Potting/Planting Soil Mix
Boating (keep towels dry, part spares, etc.)
Pesticides, Chemicals
100’s of other uses!

This is what I use them for around here…

For us personally, we have primarily been using the gamma seal lids for our bulk working inventory of wheat berries (for bread and pizza crust!), rye (mixed with wheat for bread), rice, sugar (though we don’t use that much sugar around here).

Tip regarding sugar storage: Some time ago I had purchased a big bag of sugar and dumped it in a 5-gallon bucket. Eventually it turned into a brick. Maybe because I kept it on a cold concrete floor – possibly creating condensation to some extent (enough to brick the sugar). Nowadays I just buy the small bags (4 pounders?) and set them in the bucket without dumping. Set bucket on piece of wood resting on concrete floor.

We used to use them for dry dog food too. Though our dog is now on “wet” canned food.

A Few More Tips

 Tip: With Gamma Seal Lids, avoid stacking buckets too high if the contents are heavy. This puts additional stress on the threaded lids. A typical 5 gallon pail of rice or wheat weighs about 30 pounds. If you stack them more than two high I would simply place a board between each one so the weight is transferred to the bucket’s edge (no problem).

Tip: To extend longevity and pliability of the rubber O-ring gaskets, DO NOT use petroleum jelly or petroleum based lubricants because this will eventually ruin (eat) the rubber. Instead use a silicone lube such as silicone plumbers grease:

Gamma Seal Lids are available from a number of sources, and their prices vary by quantity.

What about you? Do any of you use Gamma Seal Lids?

Like I said earlier, we like them for our working inventory of dry goods and others that we access from time to time. Easy in, easy spin.
