BRENNAN 20FJ-12MJ STR REDUCER STNLS

Description & Features

Designed for reducing between two JIC connection sizes in stainless steel hydraulic lines, the Brennan 20FJ-12MJ Str Reducer Stainless is a straight reducer fitting combining a female JIC SAE 37-degree flare end with a male JIC SAE 37-degree flare end. Both threads conform to SAE J514, with the female end sized at 1-5/8-12 and the male end at 1-1/16-12.

Constructed from stainless steel, this fitting is well suited for hydraulic systems where corrosion resistance is a priority. The straight configuration keeps the assembly compact, and the tube nut and insert design provides a reliable seal at both connection points. At 2.000 mm overall length, it fits into tight inline installations without adding unnecessary bulk. Part of Brennan Industries' Series 2406, this reducer is manufactured to consistent dimensional standards across the line.
