Thumbnail Filmstrip of 6400-06-06 | 3/8" JIC Male x #6 SAE/ORB Male Images
A 6400-06-06 | 3/8" JIC Male x #6 SAE/ORB Male hydraulic adapter is a type of hydraulic fitting that connects a JIC female fitting to an ORB (O-ring boss) male fitting. The JIC (Joint Industry Council) male fitting has a 37 degree flare on the end, which mates with a JIC female fitting, while the ORB male fitting has an o-ring on the end that creates a seal when tightened into the female ORB fitting.

A #6 hydraulic fitting refers to a fitting with a 3/8-inch nominal size, as the "#6" corresponds to the six-sixteenths of an inch (3/8") in hydraulic system terminology. The actual dimensions of the fitting may vary depending on the specific type and standard (e.g., JIC, ORFS), but the nominal size remains consistent.
To identify JIC fittings, first measure the outer diameter of the male thread or the inner diameter of the female thread using a caliper. Then, compare these measurements to a JIC thread size chart to determine the correct size, ensuring the fitting has a 37-degree flare angle, characteristic of JIC fittings.
JIC (Joint Industry Council) fittings are characterized by their 37-degree flared sealing surface, which ensures a metal-to-metal seal, primarily used in high-pressure hydraulic applications. ORB (O-Ring Boss) fittings, on the other hand, utilize an O-ring in a straight-thread design to create a leak-tight seal, making them ideal for applications requiring a robust, reliable seal against fluid leakage.
To determine the size of a hydraulic fitting, measure the outer diameter of the threads using a caliper and count the number of threads per inch to identify the thread size and pitch. Additionally, refer to a thread identification chart that corresponds to the fitting standard (e.g., NPT, BSP, JIC) to confirm the size. Always ensure you have a precise measurement to avoid mismatches in hydraulic systems.
