Description & Features

Constructed from stainless steel, this straight O-ring boss fitting connects a 1-5/8-12 Male SAE O-Ring Boss thread to a 1-1/16-12 Female SAE O-Ring Boss thread, with both ends conforming to SAE J514. The 20MORB-12FORB Straight Stnls is a reducer-style adapter suited for hydraulic lines where a size transition between these two thread sizes is required in a straight-run configuration.

The NBR O-ring seal material provides reliable sealing performance across a range of hydraulic fluids. Stainless steel construction makes this fitting appropriate for applications where corrosion resistance is a priority. Manufactured by Brennan Industries under their 6410-O series.
