A straight long configuration adaptor designed for hydraulic line connections, the 04MFS-04MORB Straight Long from Brennan Industries provides a reliable male face seal to male O-ring boss interface in a 04 to 04 size pairing. The long body design accommodates installations where additional thread engagement length or clearance is required, making it a practical choice for tight routing arrangements in hydraulic assemblies.
Manufactured by Brennan Industries, this fitting is suited for use in hydraulic systems operating with standard SAE face seal and O-ring boss port connections. The male face seal (MFS) end mates with a 37-degree flare port, while the male O-ring boss (MORB) end seals at the port face, supporting leak-free performance in demanding industrial environments.

Question by: Daryl A on Mar 18, 2026, 5:06 PM
Reckon this'll hook up okay with my existing SAE face seal and O-ring boss setups?
Answer by: Customer Support on Mar 20, 2026, 8:40 AM
This straight long adaptor is indeed designed to mate a male face seal (MFS) end with a 37-degree flare port and a male O-ring boss (MORB) end to seal at the port face. It's made to work directly with those standard SAE connections.
