Pipe sizing on williams gem units

[CraigF]

Had a call to a williams gem unit today.

The pipe sizings were a bit strange.... suction was 1/2 in but the discharge was awkward, so i got out the swaging kit, no size was right for it!!! Does this unit use some metric stuff or a mix maybe?? the liquid line also seems real heavy guage and does not swage out right yet
looks like 1/4!!

Can anyone help us??

Can anyone help us?? Only had a job the other week with unusual pipe sizing. 3/8 wasn't that or 7/16" in the flare block. Heavy gauge tube made it difficult to work with but ended up brazing in a union then running 3/8.. Mike.
