Midland Industries 6815NWO66 90 Degree Hydraulic Elbow

Product Description

The MIDLAND INDUSTRIES 6815NWO66 is a 90-degree adjustable O-ring street elbow designed for hydraulic plumbing applications. It connects a 3/8-inch male adjustable O-ring boss port to a 3/8-inch female O-ring boss port using a 9/16-18 thread. Constructed from steel, this fitting is rated for a maximum operating pressure of 3,600 psi and a maximum operating temperature of 375 degrees F. It is part of the 6815-NWO Series of SAE O-ring adapters and is intended for use by hydraulic system technicians, mobile equipment mechanics, and industrial maintenance professionals.

This fitting is suited for hydraulic circuit assembly and repair in both mobile and stationary equipment. The adjustable male O-ring boss end allows the elbow to be oriented to the desired angle during installation, which is useful in tight or awkward plumbing runs where a fixed fitting would create alignment challenges. Typical applications include hydraulic power units, cylinders, valves, and manifold porting where a 90-degree change of direction is required in the fluid line.

Key Features

• 90-degree elbow configuration for direction changes in hydraulic plumbing
• Adjustable male O-ring boss end allows rotational positioning before final torque
• 3,600 psi maximum operating pressure rating for high-pressure hydraulic systems
• 375 degrees F maximum operating temperature
• 9/16-18 thread size on both connections
• Steel construction for durability in demanding hydraulic environments

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic systems using SAE O-ring boss ports with 3/8-inch, 9/16-18 thread connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic familiar with SAE O-ring boss fittings. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect and replace the O-ring if it shows any sign of damage or wear before assembly. Tighten the adjustable end to the desired orientation and apply final torque per standard SAE J1926 fitting practices for the fitting size.
