Midland Industries 10064SS Flare Plug 1/4 in Stainless

Product Description

The MIDLAND INDUSTRIES 10064SS is a 1/4-inch SAE 45-degree flare plug manufactured in stainless steel. Flare plugs are used to cap or seal an open flare fitting on a refrigerant line, fuel gas line, or hydraulic circuit, preventing contamination and pressure loss during service or when a port is not in use. This plug features a 7/16-20 thread and measures 0.69 inches in length with a 0.43-inch hex for wrench engagement. Licensed HVAC technicians, plumbers, and gas fitters install this type of fitting as part of routine line capping, system decommissioning, or staged installation work.

This flare plug is suited for use in residential and light commercial applications where SAE 45-degree flare connections are standard. Typical installations include capping unused ports on refrigerant manifolds, fuel lines, and compressed gas systems. The stainless steel construction offers corrosion resistance in wet or chemically aggressive environments where brass may not be appropriate. It is compatible with standard SAE 45-degree flare fittings in 1/4-inch line size.

Key Features

• Compact at 0.69 inches in length, suitable for tight spaces

Compatibility

Designed as an OEM-style replacement or service fitting for systems using SAE 45-degree flare connections in 1/4-inch line size, including refrigerant, fuel gas, and compressed gas applications.

Installation Notes

Installation of flare plugs should be performed by a qualified HVAC technician, plumber, or gas fitter in accordance with applicable codes, including IFGC and local mechanical codes. De-pressurize and isolate the line before removing or installing any flare fitting. Use a properly sized wrench on the hex to avoid rounding; do not over-tighten, as flare fittings seal on the cone seat and excessive torque can damage the seating surface. Inspect the mating flare seat for nicks or deformation before installation.
