Need JD fitting ID

[Wayne County Hose]

I have to get fittings to make a no longer available steel line. I have JD part #'s for the ends but have no way of telling what is what from the part #. The steel line part # is 970704. The left nipple is 2022-20-20S, right nipple is 2040-20-20S. It is 42mm tube, 4mm wall thickness. Any help would be appreciated. Thanks, Andy.

Edit- I just found out that this is not a JD # but a tramac #. Sorry.
