What's the difference between copper fittings rated for ACR (like
Mueller or Nibco 96XX) vs. standard copper fittings sold at H/W
stores.

Is there any issue in using the generic wrot copper fittings for HVAC
use?

Have you ever used a standard fitting in a pinch?

the copper fittings & pipe sold in hardware stores is for water, not
refrigeration. different operating pressures ya know.

plus, i've never seen a long radius copper ell in a hardware store.

Slightly different sizes. 7/8 ACR is same as 3/4 water copper.
ACR is outside diameter, and water is inside.

Is sizing the only difference?? Would a 7/8" ACR coupling be
identical to a 3/4" water coupling? (ie nothing different about the
metalurgical properties of the copper that make it better for HVAC)

TIA
