The tighter the better, right? Nope. Not with Gamma Seal lids. When you close your Gamma lid, you want to spin it until it stops and then tighten it down just a tiny bit more, about a quarter inch. Yes, I know, if you really crank on it, you can easily get the lid to turn two or even three inches more and give yourself a feeling of satisfaction knowing that the contents of your pail are safe and snug. Problem is that you’ll eventually ruin the gasket on the lid this way. And the extra torquing is unnecessary, even damaging.
What happens when you twist the lid on so tight is you squeeze the gasket between the lid and the pail much harder than it needs to be squeezed, stretching the gasket a little while you turn. In so doing, you mis-shape the gasket a little bit each time you close the lid too tightly. And eventually, it will weaken the seal.
So save your amazing strength for more productive things like hand grinding your wheat or hoisting your two year old up on the counter to help you knead bread dough. And only tighten the Gamma lid down about a quarter of an inch after it stops spinning closed on its own. This will ensure your Gamma Seal lids retain their excellent air and water tight seals for many years to come.
