10FORB-12MP STRAIGHT

Description & Features

Manufactured from straight steel, the 10FORB-12MP Straight is a hydraulic adapter fitting from Brennan Industries designed to connect a 7/8-14 Female SAE O-Ring Boss port (per SAE J514) to a 3/4-14 Male NPTF thread (per SAE J476). The female ORB end provides a leak-resistant sealed connection at the port side, while the male NPTF thread forms a pressure-tight mechanical seal on the pipe thread end.

Part of Brennan's 6404 Series, this straight adapter is suited for use in hydraulic circuits where an ORB port must be transitioned to an NPTF-threaded component. With an overall length of 1.850 mm, it is a compact inline fitting appropriate for space-constrained installations. California residents should note this product carries a Prop 65 warning.

got a valve block with a 7/8-14 ORB port and i need to go over to 3/4-14 pipe thread. is this the right adapter?
Answer by: Customer Support on Dec 19, 2025, 7:02 PM
For that setup, it matches the thread types and sizes shown: a 7/8-14 Female SAE O-Ring Boss (SAE J514) on one end and a 3/4-14 Male NPTF (SAE J476) on the other, in a straight inline adapter.
