This is the best way to lubricant any type of gasket with a silicon lubricant. Loaded with enough silicon 747 grease to lubricant hundreds of gaskets. Simply place the gaskets inside and give a 1/2 turn of the lid, with very light pressure and you are done. When dry just add a little more silicone 747, which you can purchase below.
