Midland Industries 706104-12 Brass Pipe Union 3/4 Fpt

Product Description

The MIDLAND INDUSTRIES 706104-12 is a lead-free brass pipe union designed for joining and disconnecting threaded pipe runs without cutting. Both end connections are 3/4-inch female pipe thread (FPT), making it a straight union suited to copper, brass, or steel pipe systems. The body is manufactured from lead-free brass, keeping the fitting compliant with potable water standards. Overall length measures 1.9 inches with a hex size of 1.68 inches across flats. The union design allows the line to be broken and re-made at a single point, which is essential for equipment service access in tight piping runs. Plumbers and pipefitters install this fitting in residential and light commercial applications.

This union is appropriate for residential and light commercial water supply, hydronic heating, and general plumbing systems where a serviceable connection is required in a threaded pipe run. The 3/4-14 thread spec confirms standard NPT engagement. Its lead-free brass construction meets the requirements of applications involving potable water distribution. The fitting is compatible with both brass and steel pipe, giving installers flexibility when working with mixed-material systems. It is well suited to mechanical rooms, boiler rooms, water heater connections, and other service-accessible piping locations.

Installation Notes

Installation is performed by licensed plumbers in accordance with the International Plumbing Code (IPC) and applicable local codes.

Tighten with a pipe wrench to the hex flats - do not overtighten, as brass threads can be damaged by excessive torque.
