Midland Industries 10059 Hex Reducing Nut Sae 45 Deg Flare Brass

Product Description

The MIDLAND INDUSTRIES 10059 is a forged brass hex reducing nut designed for SAE 45-degree female flare connections in hydraulic tubing systems. It steps down from a 1/4-inch connection to a 3/16-inch connection using a 7/16-20 thread size, making it a straightforward solution when two different tube sizes need to mate at a flare joint. Rated to 1400 psi and functional across a temperature range of -65 to 250 degrees F, this fitting handles the demands of working hydraulic lines. The forged brass construction provides corrosion resistance and the mechanical strength required for reliable, leak-free joints. Plumbers, HVAC technicians, and fluid-system mechanics are the typical installers.

This reducing nut is suited for use with aluminum, brass, copper, and steel hydraulic tubing in both residential and light commercial applications. The SAE 45-degree flare standard is common in refrigeration lines, fuel systems, and hydraulic plumbing where a dependable metal-to-metal seal is required. With a 0.03-inch tube wall thickness specification, it is matched to standard-wall tubing in these systems. Its compact profile fits into tight plumbing assemblies without requiring additional adapters or fittings.

Compatibility

Compatible with aluminum, brass, copper, and steel hydraulic tubing conforming to the SAE 45-degree flare standard with a 0.03-inch tube wall thickness.

Installation Notes

Installation is performed by a qualified plumber, HVAC technician, or hydraulic systems mechanic. Always depressurize and drain the line before removing or installing any flare fitting. Hand-tighten the nut onto the flare seat first, then use an appropriately sized flare wrench to avoid distorting the hex. Follow all applicable codes, including IPC and IFGC provisions, for the specific fluid and system type being serviced.
