Midland Industries 64001224 Male Jic X Male Orb Adapter

Product Description

The MIDLAND INDUSTRIES 64001224 is a steel hydraulic adapter designed to connect a 3/4-inch Male JIC fitting to a 1-1/2-inch Male O-Ring Boss port. Thread sizes are 1-1/16-12 on the JIC end and 1-7/8-12 on the O-Ring Boss end. Rated to 2900 psi working pressure and 375 degrees F maximum operating temperature, this adapter is built for demanding hydraulic plumbing applications. Non-adjustable pressure range runs from 3600 to 2300 psi. The one-piece steel construction provides reliable sealing integrity in high-pressure hydraulic circuits. Hydraulic system technicians and fluid power mechanics are the primary installers.

This adapter fits into hydraulic systems requiring a transition between JIC 37-degree flare connections and O-Ring Boss ports. It is used in mobile equipment, industrial machinery, and hydraulic power units where dissimilar port types must be joined. The compact profile - 2.4 inches in length and 2.1 inches in height - suits tight plumbing runs in equipment bays and under-hood installations. The 6400 Series designation places it within a standard product family of steel JIC-to-Male O-Ring adapters used across industrial and mobile hydraulic applications.
