Manufactured by Brennan Industries, this straight adapter fitting connects a 20 series metric JIC male thread to a 12 series male O-ring boss (ORB) port, making it a practical solution for joining metric and inch-standard hydraulic lines in a single inline connection. The straight configuration keeps the assembly compact where space and routing constraints call for a direct, non-angled transition.
The 20MJ-12MORB Straight is suited for use in hydraulic circuits where metric JIC and ORB port interfaces must be bridged without additional adapters. Brennan Industries fittings are widely used across mobile equipment, industrial machinery, and fluid power systems that require reliable threaded connections.

Question by: Dwayne W on Nov 21, 2025, 6:21 PM
Got a metric JIC line coming off a pump and need to tie into an ORB port on a valve block, this the right fitting for that?

That's what this one's built for. One end is a 20 series metric JIC male thread, the other is a 12 series male O-ring boss. So if you've got a metric JIC line that needs to seat into an ORB port, this straight adapter bridges that connection in a single piece without stacking extra fittings in between.

got a hose with a 20 series metric JIC male on it and the other side needs to go into a 12 series ORB port. is this the right straight adapter?

It bridges a 20 series metric JIC male thread to a 12 series male O-ring boss (ORB) port in one inline, straight connection, so it’s meant for exactly that metric-to-inch interface change.
