04MJ-08MORB STRAIGHT

Description & Features

Manufactured by Brennan Industries, this straight hydraulic adapter provides a reliable male JIC 37° flare to male O-ring boss connection in a compact, inline configuration. The 04MJ-08MORB straight fitting connects a -04 JIC male end to a -08 male O-ring boss port, making it well suited for routing hydraulic lines between components with differing thread standards.

Straight adapters in this configuration are commonly used in mobile and industrial hydraulic circuits where a direct, non-angled transition between JIC and ORB ports is required. The O-ring boss end provides a leak-resistant seal at the port face, while the JIC end relies on a metal-to-metal 37° flare seat for a secure fluid connection.

What size is each end of this thing? Just want to make sure it'll fit my setup.

It adapts a -04 JIC male end to a -08 male O-ring boss port. This makes it handy when you're connecting hydraulic lines between different thread standards.
