12MFS-16MORB Straight Stnls

Ask A Question

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.

Question by: Randy W on May 3, 2025, 10:25 AM
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.
