Rigid pipe is described by inner diameter (so 3/4" pipe is about 7/8" outside). Tubing ("soft" copper) is described by outer diameter. Tubing is usually connected by compression fittings, but you can solder it with the proper fittings.

ah d'oh .. it's 7/8" pipes. And yes they're sold online. The 7-11'ish (small-box, but close-by/convenient) Ace Hardware doesn't carry 7/8".

How to measure HVAC & Refrigeration tubing Refrigeration tubing is measured by it's outside diameter O.D: 1/4, 1/2, 5/8, 3/4, 7/8, 1-1/8, 1-3/8, 1-5/8, etc.
Plumbing tubing is measured by it's inside diameter I.D: 1/8, 1/4, , 1/4, 1, 1-1/4, 1-1/2, 1-3/4,etc.Rule of Thumb: "HVAC" nominal tube sizing 1/8; larger than the same nominal size "plumbing" pipe.
So for example, a 1/4" HVAC fitting, is the same as a 1/8" Plumbing1fitting. Or a 1/2" HVAC fitting, is the same as a 1/4" Plumbing fitting.
For HVAC a 1/2" fitting, will fit on a pipe that's 1/2" on the "outside" (OD), as the fitting ha
