Bill, From the pictures, I can’t tell if these are metal braids or cloth braids on the hoses. If metal braids, check out SWAGELOK as they have stainless braid hose, 1/2 inch inside diameter, 37 degree bevel (flare) fittings and 12 inches long (P/N: SS-CT8AS8AS8-12). I have dealt with the Raleigh NC office for several years and their service is excellent.
Another source (perhaps with cloth braid, if that is what you need) may be Raleigh-Durham Rubber and Gasket. I have purchased custom hose and gaskets from them in the past and they carry a wide selection (Web: http://www.raleighdurhamrubber.com/ ) (Raleigh Phone: 800-662-7577). Good luck with your project.
