Constructed from stainless steel, the 12MJ-12MORB Straight Stnls is a straight hydraulic adapter designed for high-pressure fluid line connections in demanding industrial environments. Both end threads are sized at 1-1/16-12, with one end configured as a Male JIC SAE 37-Degree Flare and the other as a Male SAE O-Ring Boss, allowing direct transition between these two common connection standards. Both threads conform to SAE J514.
Rated to 5,000 PSI maximum dynamic pressure, this fitting is well-suited for hydraulic circuits where corrosion resistance and connection integrity are priorities. The O-ring seal uses NBR material, providing reliable sealing performance across a broad range of hydraulic fluids. Part of Brennan Industries' 6400-O series, this stainless steel adapter is California Prop 65 compliant as noted by the manufacturer.
