04MORB-04FORB STRAIGHT REDUCER

Description & Features

Designed for same-size inline connections, the 04MORB-04FORB Straight Reducer provides a male-to-female SAE O-Ring Boss interface using matching 7/16-20 threads on both ends, conforming to SAE J514 at each connection point. The straight configuration keeps hydraulic line routing compact where a direct in-line transition is needed.

Constructed from steel, this fitting uses an NBR O-ring seal for reliable, leak-resistant performance in hydraulic circuits. Both thread ends follow SAE O-Ring Boss geometry, which relies on a face seal to prevent leakage rather than thread-to-thread contact alone. With an overall length of 1.100 mm, the fitting maintains a low-profile footprint suited to space-constrained assemblies. Manufactured by Brennan Industries as part of the 6410-O series, it carries a Proposition 65 warning for California residents.
