Midland Industries 704014-05 Flare Short Rod Nut 5/16in

Product Description

The MIDLAND INDUSTRIES 704014-05 is a SAE 45-degree flare short rod nut designed for secure, leak-resistant flare connections in refrigeration, HVAC, and plumbing lines. Manufactured from lead-free brass, this fitting meets current potable-water and refrigerant-line safety requirements. The female flared connection accepts a 5/16-inch tube end finished to the SAE 45-degree flare standard. It carries a 1/2-20 thread size and is rated for service from -40 degrees F to 250 degrees F, making it suitable for a broad range of fluid and gas applications encountered in the trades.

This short rod nut is used where a compact flare coupling is needed on copper, brass, aluminum, or steel tubing runs. Typical applications include residential and light commercial HVAC refrigerant lines, compressed air systems, fuel-gas distribution, and hydraulic or pneumatic tubing assemblies. The short-body profile is well suited for installations with limited wrench clearance. HVAC technicians, plumbers, and pipefitters regularly specify this fitting when replacing worn or damaged flare nuts on existing assemblies.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or pipefitters. Always depressurize and evacuate the line before removing or installing flare fittings. Inspect the tube flare for cracks, ovality, or surface defects before tightening; a damaged flare seat will not seal correctly regardless of torque applied. Follow applicable codes, including ASHRAE 15, IFGC, and IPC, for refrigerant and fuel-gas line work.
