Description & Features

A straight long male fitting designed for use in hydraulic tube and port connections, the 08MFS-08MORB Straight Long connects a 1/2 in. OD tube end to an O-ring boss (ORB) port. The fitting uses a 13/16-16 thread on the flare side and a 3/4-16 thread on the ORB side, with a hex size of 0.875 in. and an overall length of 2.671 in. The extended length accommodates installations where standard-length fittings cannot reach the port or where additional clearance is needed between components.

Manufactured by Brennan Industries under the FS6400-L-O series, this fitting is suited for hydraulic systems requiring a reliable, leak-resistant ORB port connection. The O-ring face seal and male flare configuration provide a secure, vibration-resistant joint in demanding industrial applications.
