Twinflex Professional 904 Liner

316 is a high quality steel: 904 is virtually an exotic, so exotic that it is not readily available commercially. We use it because it is the highest possible quality for this type of use. It is, of course, much more expensive, about twice the price of 316 but when you consider the overall cost of the installation, it is worth every penny.
