[QUOTE="SLK50, post: 280437, member: 4790"] Hi WW, Tubing would ordinarily be sized by it's inside diameter, no consideration given to it's thickness. Fittings would be sized by their outside diameter. Assuming all fittings are male to fit into the tubing. Hence a 3/16" fitting would fit into 3/16" tubing and so forth. Tubing is commonly used a little undersized ( 1/32" ) to insure a snug fit and no leaks. I used a 3/16" drill bit as a visual gauge to size up the ports on my CC and TB's and purchased check valves ( 3/16" ) and tubing ( 5/32" ) to match. All connections were smooth yet snug with no undue stress to tubing or fittings. Tight enough so there's chance of a vacuum leak yet I can still disassemble it if I have to without breaking any fittings. Good luck with your project. [/QUOTE]
