Midland Industries 704048-0202 Flare Half Union Adapter

Product Description

The MIDLAND INDUSTRIES 704048-0202 is a SAE 45-degree flare half union adapter designed to connect 1/8-inch male flared tubing to a 1/8-inch male NPTF threaded fitting. Manufactured from lead-free brass, this compact adapter measures 0.85 inches in length, 0.40 inches in width, and 0.35 inches in height. The 5/16-24 flare thread mates with a 1/8-27 NPT thread, making it a standard transition fitting used in refrigeration, HVAC, and plumbing applications. It is rated for a temperature range of -40 to 250 degrees F and is suited for use in systems where lead-free materials are required by code.

This adapter is used in residential and light commercial applications where a SAE 45-degree flare connection must transition to a male NPTF pipe thread. It is appropriate for use with copper, brass, aluminum, and steel tubing. Typical install scenarios include refrigerant line connections, fuel gas distribution, and compressed air or hydraulic systems requiring a reliable flare-to-male-pipe transition. The lead-free brass construction meets requirements for potable water and other code-sensitive environments.

Compatibility

Designed for use with copper, brass, aluminum, and steel tubing in SAE 45-degree flare systems requiring a male NPTF pipe thread connection. Suitable for HVAC, refrigeration, plumbing, and fuel gas applications where lead-free fittings are specified.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanic depending on the application. Shut off all system pressure and isolate the line before making or breaking any flare connection. Do not over-tighten the flare nut against the seat, as this can distort the flare and cause leaks. Thread sealant on the NPTF male threads should be applied per the system manufacturer or applicable code requirements such as the IPC or IFGC.
