Product Questions & Answers

Will this fit my Komatsu equipment alright? Just want to be sure before I order.

This union adapter is designed to connect male JIC fittings to male Komatsu fittings. On the JIC side, it fits a 3/4" size with 1-1/16 - 12 UN callout. The Komatsu side fits a 30mm size with a 20mm callout.

Got a Komatsu machine that's leaking at the fitting and I need to swap in a JIC line from my other setup. This union here, the 9237-12-30, will it bridge those two together without needing extra adapters in the middle?

One end threads directly into a Komatsu port at 20mm and the other end connects to a 3/4" JIC male fitting at 1-1/16-12 UN, so yeah, that single piece handles the transition. No additional adapters needed in between. Both sides are male, so make sure the mating ports on your line and your machine are female on each end before ordering.
