Description & Features

A straight steel hydraulic adapter rated to 5,000 PSI dynamic pressure, the 06MJ-03MORB Straight connects a 9/16-18 Male JIC SAE 37-degree flare on one end to a 3/8-24 Male SAE O-Ring Boss on the other. Both threads conform to SAE J514, making this a reliable inline transition between JIC and ORB-ported components in hydraulic circuits.

The NBR seal material provides compatibility with common petroleum-based hydraulic fluids. California residents should note this product is subject to Proposition 65 requirements.
