3/4” OD copper pipe question
Can't be fixed this way. You let all the juice out anyway. Call an Hvac pro. Lineset/system needs nitrogen flowed and brazed for the repair. Then pressure test, vacuum, recharge. More on reddit.com

April 27, 2025I need advice. The OD on my 3/4 in copper pipe is larger than .875 so my compression fitting are too small. The OD is about .92. I'm installing a water heater. What should I do?
Heat it up and take the piece of copper out of the fitting. Then solder in an MIP x pex fitting. And save your self 10% by switching to Geico. More on reddit.com

r/Plumbing on Reddit: 3/4” OD copper pipe question
April 27, 2025 -
Accidentally drilled a hole in one of the refrigerant lines of my AC unit on the outside of my house and want to repair it. The pipe is 5/8” (3/4” OD), and Home Depot only had 1/2” or 3/4” sharkbait couplers. I can’t seem to find any that would fit 5/8”, and it’s Sunday so plumbing supply stores are closed . I already cut the pipe above the hole so I can’t use one of those quick repair wrap kits. What are my options? Total DIYers here, not a plumber by any means.

HVAC tubing is not the same size as plumbing piping. Though both are copper they are not of the same type or diameter. Tubing is sized OD and piping is ID. As stated above this will need to be repaired correctly and recharged with whichever refrigerant your system requires. Not necessarily a DIY repair unless you have the appropriate knowledge and tools to complete. Done incorrectly can damage your system.

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".

August 22, 2020 - There is a tolerance on fittings...some fit better than others. Also, be triple sure the pipe is still round, and hasn't turned oval. You can do this with an adjustable wrench ... If I remember right Harddrawn copper tubing nominal pipe size is measured Inner-diameter where as soft/felxible copper tubing nominal pipe size is measured by outer-diameter you cannot/shouldn't use compression fitting on hard drawn copper.
