24MJ-20MORB Straight

You’re looking at a straight steel adapter with a Male JIC SAE 37 degree flare on one end (1-7/8-12 thread) and a Male SAE O-Ring Boss on the other (1-5/8-12 thread). It’s built to SAE J514 on both sides and uses an NBR O-ring for the ORB seal.

This fitting is rated for a maximum dynamic pressure of 3,000 psi, so it's built to handle quite a bit in demanding hydraulic systems.

3,000 psi is the maximum dynamic pressure rating, so that accounts for the system being under active load, not just static conditions. Running a hydraulic press continuously at or near that ceiling would be pushing the limits. Most folks size their fittings with some headroom below the rated max to account for pressure spikes and long-term wear. If your system is regularly spiking close to 3,000 psi, you'd want to factor that in when deciding if this is the right fit for your setup.
