Just some input from an ole marine engineer. We loved 316 SS tubing and Swagelok fittings. SwageLok is a compression type fitting - much easier to use that 37 degree flares. Also, a proper flaring tool for stainless can be quie expensive. The Imperial Eastman benders are nice as are the cutters. These benders are lever type and require some time to master. The coil type copper tubing benders won't really work with the stainless. Remember that your ordinary copper tubing cutter will not cut stainless either, unless you replace the cutter wheel. If at all possible buy your tubing in straight lengths rather than coiled as the final job will be more professional looking.
