    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 has an opening of 1/2".But for plumbing it will fit onto a pipe that is 1/4" on the "inside" (ID) which equals to 1/2 on the outside.
