Male Jic X Male Komatsu Union

Ask A Question

Description & Features

Constructed from steel in a straight configuration, this union connects a 9/16-18 UNF male JIC fitting on one end to a male Komatsu port on the other, bridging two common but incompatible thread standards in a single compact body. The JIC side accommodates a 3/8" line, while the Komatsu side carries an 18mm thread with a 20mm callout. Overall length is 39.8mm, with a 19mm wrench flat for installation.

The Male JIC X Male Komatsu Union is an Adaptall product, suited for hydraulic circuits where JIC-threaded lines connect to Komatsu-ported equipment. The straight geometry keeps routing direct, and steel construction provides the durability expected in hydraulic service environments.

Got a Komatsu machine with a JIC line running to it, this union piece the right call for tying those two together?

That's what it's built for. One end is a 9/16-18 UNF male JIC to handle a 3/8" line, and the other is a male Komatsu port with an 18mm thread. The straight body keeps things clean and direct without any angle routing. Steel construction holds up in hydraulic service without any fuss.

got a hose end that’s 9/16-18 JIC for a 3/8 line, will this union let me hook it to a Komatsu port?

For connecting those two standards, it bridges a male 9/16-18 UNF JIC end sized for a 3/8 inch line to a male Komatsu end with an 18 mm thread and a 20 mm callout, all in a straight steel union.
