I use the adapter all the time and never heard of keeping the lids warm for a better seal. I could use a better seal. What do you do to warm the lids?

Thanks for the tip.

I give them a dip in boiling water then dry them with a paper towel before quickly sealing with the vac sealer. Seems to work well.

Me too. The seal I have is such a perv.

Ditto post #8, just make sure they are very dry—work quickly. The boiling water softens the little band of rubber making it more pliable for improved seal.
