got a hose with a 9/16-18 JIC male on it, will this union mate up on that side or am i off a size

On the JIC side, it has a 9/16-18 UNF male thread and it is called out as a 3/8 inch JIC size, so it matches a 9/16-18 JIC female connection.

What size is the JIC end on this fitting? I need to make sure it'll match what I got.

The JIC side is a 3/8" size with a 9/16 - 18 UNF callout.

Got a Komatsu port on a piece of equipment and need to tie it into a JIC line, this union do the trick for a straight connection?

That's what this fitting is built for. One end is an 18mm Komatsu male, the other is a 9/16-18 UNF JIC male, and it runs straight through with no bends or offsets. At 40.3mm overall length it's pretty compact, so it'll fit in tighter spots without much fuss. Steel construction keeps it solid for hydraulic line work.
