Generally all brands are made on the same machine drossbach's or metal flex's but their have been different locks over the years. I like to think of the service of the company and the components more then the liner. Also, their are different thickness's of liners but I prefer .005 alot of people pride .006 as being better but it is cheaper to make due to the metal not having to be rolled down as thin and some manufacturers use that as a deceiving reward to sell the product.

There are some differences. Some have welded seams. Some are more crush resistant. Some straighten more easily. Some are more resistant to damage during tight installs.

It is at least 5x the thickness of conventional chimney liner. It unrolls flat with no extra bending to makie it run straight, and very heavy duty. once you get it going it guides itself down the chimney with little prodding. You need a Metal blade and saw to cut it, no way a pair of tin snips will cut this. It's harder to lug up the roof, but easier to work with, is actually more compact that a regular thin wall ss liner because it does not need the large corrugations to maintain rigidity. Slides down a 7x7 flue where most of the standard 316 liners hang up. Next time you see a dump truck, take a look at the exhuast pipe, where it comes out from the chassis and goes to the vertical stack. That heavy flex pipe you see is basically how elmer's makes their liner.

Good luck with that. Six inches is the inside diameter of the pipe. Not the outside.
It ain't gonna happen.
Only three times the thickness... and their is a reason they use that material it's because it is cheaper to buy (not saying it makes or does not make a better liner just informing). The way metal is produced the thinner it is the more yield you get. For example if you cut flashings out of 24 gauge it may seem cheaper then cutting out of 20 gauge because you get more pieces of material for a price of a sheet of metal. The downside is, is that the metal has to be re-rolled to be thinner and thus cost more because more processes are added to the cost of the metal. Most manufacturers found that .005 or .006 is a good grade on cost and flexibility to what the customer wanted. Just an FYI

For what it is worth, nobody has reported any flex liner crapping out on them in the four years I have hung out here. One dealer I talk with on the side has been installing them for twelve years and hasn't had one fail yet. And his people sweep them with steel brushes.
That's in regard to not overfiring the stove.... I heard a story recently where the recipient overfired her stove so that the door cracked and thought that the warranty on the liner should be replaced as well. Liners are their to protect you- like air bags they have a life span.
