Gamma Seal Lids – And Here’s Why You Want Them…

Last updated on May 19th, 2018

Gamma Seal Lids

Gamma Seal Lids are specially designed to fit the top of a typical 5 gallon plastic bucket (actually they fit 5 and 6 gallon buckets due to a standard diameter).

They make for easy-on, easy-off lid 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.

Are they worth the money? Sure, yes. And here’s why…

While some may say that Gamma Seal Lids are expensive, there are use cases where it’s so convenient that it’s worth the money (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 Lids

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.

100’s of other uses!

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:
