Midland Industries 10023 Hex Reducing Short Rod Nut Brass

Product Description

The MIDLAND INDUSTRIES 10023 is a hex reducing short rod nut designed for SAE 45-degree flare connections in hydraulic and fluid system applications. This brass fitting transitions between a 3/8-inch and 1/4-inch connection, making it a practical solution when two different line sizes meet at a single joint. The body measures 0.74 inches in length with a 0.81-inch hex, and the 5/8-18 thread size and 0.032-inch minimum tube wall specification ensure compatibility with standard hydraulic tubing. Rated to 1000 psi and a temperature range of -65 to 250 degrees F, this fitting handles demanding service conditions in both stationary and mobile equipment.

This fitting is suited for use with copper, brass, aluminum, and steel hydraulic tubing in residential, commercial, and industrial fluid system work. The SAE 45-degree flare connection style is common in refrigeration lines, hydraulic circuits, fuel systems, and compressed air plumbing. Technicians and plumbers working on reducing connections between mismatched tube sizes will find this nut provides a reliable, leak-resistant joint when properly flared and torqued to specification.

Compatibility

Designed for use with copper, brass, aluminum, and steel hydraulic tubing using SAE 45-degree flare connections. Requires a minimum tube wall thickness of 0.032 inches.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified hydraulic systems technician. Shut down and depressurize the hydraulic or fluid system completely before disassembling any fittings. Ensure tubing ends are cut square, deburred, and properly flared to SAE 45-degree specification before seating the nut. Do not overtighten; follow the applicable system manufacturer torque guidelines and relevant IPC or SAE standards for flare fittings.
