Midland Industries 12008 3/4 in Male Inverted Flare Nut Steel

Product Description

The MIDLAND INDUSTRIES 12008 is a 3/4-inch male inverted flare nut used to create secure, leak-resistant connections in hydraulic and fluid-transfer tubing systems. Manufactured from steel with a zinc chromate finish for corrosion resistance, this nut measures 0.88 inches in length with a 1.06-inch hex for wrench engagement. It is rated to 550 psi and performs across a temperature range of -65 to 250 degrees F. The 1-1/16-16 thread size is a standard inverted flare specification. Plumbers, HVAC technicians, and hydraulic system installers use this fitting in both service and new-install applications.

The 12008 is suited for use with aluminum, brass, copper, and steel hydraulic tubing, making it a versatile choice across a range of fluid-line assemblies. Typical applications include hydraulic brake lines, refrigerant lines, fuel lines, and other low-to-medium-pressure tubing runs where an inverted flare connection is specified. Its steel construction and zinc chromate coating make it appropriate for environments where light corrosion resistance is needed without the cost of stainless or brass alternatives.

Installation Notes

Installation should be performed by a qualified technician familiar with hydraulic or refrigerant tubing systems. Depressurize and drain the line completely before removing or installing any fitting. Use a properly sized flare tool to prepare the tubing end before seating the nut; do not overtighten, as inverted flare fittings rely on metal-to-metal contact and excess torque can damage the seat. Follow applicable system codes and manufacturer specifications for the assembly being serviced.
