Midland Industries 704055-10 Flare Union Elbow 5/8 in

Product Description

The MIDLAND INDUSTRIES 704055-10 is a lead-free brass SAE 45-degree flare, 90-degree union elbow designed for use in refrigeration, HVAC, and fluid-handling tubing systems. It features a 5/8-inch male flared connection on both ends, making it a union-style fitting that allows the joint to be disconnected without cutting the tubing. Rated for temperatures from -40 to 250 degrees F, it is suited for both low- and medium-temperature applications. The 7/8-14 thread specification confirms SAE standard fitment. Licensed plumbers, HVAC technicians, and refrigeration mechanics typically install this type of fitting.

This elbow is intended for applications requiring a 90-degree directional change in a flare-connected tubing run. It is compatible with aluminum, brass, copper, or steel tubing, making it a versatile choice across residential and light commercial HVAC, refrigeration, and plumbing installations. The union design allows the fitting to be serviced or replaced without disturbing the rest of the tubing assembly, which is useful in tight equipment spaces where tubing cannot be easily rotated.

Key Features

• SAE 45-degree flare seats on both ends for a leak-resistant metal-to-metal seal
• 90-degree union elbow design allows directional routing and in-line serviceability
• Lead-free brass construction meets regulatory requirements for potable and non-potable fluid systems
• Compatible with aluminum, brass, copper, or steel tubing
• Rated from -40 to 250 degrees F for broad application range
• 7/8-14 SAE thread on both connections

Compatibility

Designed for use with aluminum, brass, copper, or steel tubing in SAE 45-degree flare systems. Both connection ports are 5/8-inch male flared with a 7/8-14 thread.

Installation Notes

Installation should be performed by a licensed HVAC technician, refrigeration mechanic, or plumber. Shut off and depressurize the system fully before disconnecting any flare fittings. Use a properly calibrated flaring tool to ensure the tubing flare angle matches the SAE 45-degree seat. Do not overtighten flare nuts, as this can crack the flare or distort the seat and cause leaks.
