Midland Industries M4601-06-M18 90-deg Elbow Fitting

Product Description

The MIDLAND INDUSTRIES M4601-06-M18 is a 90-degree elbow fitting designed to connect a 3/8-inch beaded hose stem to an M18 male adjustable O-ring boss (ORB) port. Part of the 4601 Series, this steel hydraulic fitting creates a right-angle transition in a hydraulic line, allowing installers to route hose efficiently in tight or constrained plumbing layouts. The M18 x 1.5 threaded end provides a leak-resistant adjustable ORB connection that can be clocked to the desired orientation before torquing. Hydraulic technicians and fluid power mechanics install this fitting in industrial and mobile hydraulic systems.

This fitting is suited for steel beaded hose assemblies in hydraulic circuits where a 90-degree directional change is required. Typical applications include mobile equipment, agricultural machinery, and industrial hydraulic power units where hose routing must clear structural members or adjacent components. The adjustable ORB port end allows the fitting orientation to be set independently of the final torque position, simplifying assembly in confined spaces.

Key Features

• 90-degree elbow geometry for right-angle hose routing in hydraulic systems
• 3/8-inch beaded stem end secures hose with a clamp or ferrule
• M18 x 1.5 male adjustable O-ring boss thread for leak-resistant port connections
• Adjustable ORB end can be clocked to desired orientation before final tightening
• Steel construction for durability in hydraulic fluid service
• 4601 Series design for beaded hose to male adjustable O-ring elbow applications

Compatibility

Designed as an OEM-style hydraulic elbow fitting for systems using 3/8-inch beaded hose and M18 x 1.5 male adjustable O-ring boss ports in steel beaded hose hydraulic plumbing circuits.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and fully relieve hydraulic system pressure before removing or installing any fittings. Ensure the O-ring is properly seated and lightly lubricated before threading the ORB end into the port. Clock the fitting to the required hose routing angle before applying final torque to the adjustable nut.
