Can someone point me to a source for dimensions of HVCR fittings? Thanks in advance.
 
See SMACNA (Sheet Metal and Air Conditioning Contractors National Association) standards.
 
Thanks everyone. All good info. The references don't seem to give the actual dimensions of the connections, male & female, though. Are these the same as 37° flare, MS33649, J1926, MS16142, or J514?

37* flare is used on steel tubing, whereas 45* flare is used on copper. Steel tubing is harder to flare thats why they use 37* flare.
