Review on Gamma Seal Lid 6 Pack by Tabitha Johnson

TankFarm, the seller through Revain packaged them nicely and included a moisture monitoring card as a bonus. It's good to know that what you're storing has too much moisture on the color chart. We've been using Gamma Seals since 1998. The originals had spots around the edges where dust could collect. This new type doesn't dust like the old ones. Additionally, there is a thicker o-ring for a tighter fit on the top of the bucket.
