12MJ-20MORB STRAIGHT STNLS

Description & Features

Constructed from stainless steel, the 12MJ-20MORB Straight Stnls is a straight hydraulic adapter rated for dynamic pressures up to 4,000 PSI. It connects a 1-1/16-12 Male JIC SAE 37-degree flare (Thread B1) to a 1-5/8-12 Male SAE O-Ring Boss (Thread B2), with both threads conforming to SAE J514. The O-ring seal is NBR material, providing reliable fluid containment at the connection interface.

Part of the Brennan Industries 6400-O series, this fitting is well suited for hydraulic circuits where a transition between JIC flare and O-Ring Boss terminations is required in a straight inline configuration. Stainless steel construction makes it appropriate for environments where corrosion resistance is a priority.
