Male Orfs X Male Komatsu

Description & Features

A straight steel adapter connecting a 1-7/16-12 UN male ORFS thread on one end to an M33 x 1.5 male Komatsu thread on the other, this Male Orfs X Male Komatsu fitting is manufactured by Adaptall for reliable performance in hydraulic systems requiring cross-standard thread compatibility. The straight profile keeps routing straightforward where space allows.

Built from steel with a 41mm wrench width and an overall length of 61.9mm, this adapter is well-suited for mobile equipment and heavy machinery applications where Komatsu-pattern ports need to interface with ORFS-terminated lines. The 1-inch ORFS side and 33mm Komatsu side are both male, making it a direct male-to-male transition fitting.

Got a Komatsu port on a piece of heavy equipment that needs to tie into an ORFS line, this the right adapter to make that happen?

That's what this fitting is built for. One end is a 1-7/16-12 UN male ORFS thread, the other is an M33 x 1.5 male Komatsu thread, so it bridges those two standards in a single straight adapter. Both sides are male, which means you'll need female counterparts on whatever you're connecting to. The straight profile keeps things clean when you've got the clearance to work with.

got a komatsu port that’s M33 x 1.5 and my hose end is 1 inch ORFS, is this the right adapter?

Answer by: Customer Support on Nov 12, 2025, 6:55 AM

For that exact thread mix, it matches up as a straight male to male adapter with M33 x 1.5 male on one side (Komatsu) and 1-7/16-12 UN male on the other side (1 inch ORFS).
