    You failed to include the stainless clamp ring system. Clamp rings work with the same fittings as crimp rings and in my opinion are superior. The clamp rings won’t corrode, use a singe less expensive tool that does not require adapters for different tubing sizes, the tool is easier to use in tight spaces, and the clamp rings are far easier to remove if one makes a mistake or needs to change out a fitting.
