12MFS-16MORB Straight Stnls

Description & Features

Constructed from stainless steel, this straight hydraulic adapter connects a 3/4 inch male flareless fitting (12 MFS) to a 1-5/16-12 male O-ring boss (16 MORB) port. The straight configuration suits inline installations where a direct, low-profile connection is needed between these two thread types. The 12MFS-16MORB Straight Stnls is part of Brennan Industries' FS6400-O series and carries a 1-1/2 inch hex for standard wrench engagement.

Thread dimensions measure 1-3/16-12 on the flareless end and 1-5/16-12 on the ORB end, with an overall length of 1.958 inches. Both ports share a 0.609 inch drill diameter. Stainless steel construction makes this fitting well-suited for hydraulic circuits exposed to corrosive media or environments where carbon steel is not appropriate.

Will this fitting hold up if I'm usin' it with some pretty harsh chemicals?
Answer by: Customer Support on May 4, 2025, 9:03 PM
Being made from stainless steel, this fitting should definitely hold up in hydraulic systems where you're dealin' with corrosive stuff that would eat away at regular carbon steel.
