Union Configuration
Threaded End
One end connects to compatible threaded pipe, fittings, valves, or equipment and remains installed as part of the piping system.
Union Nut & Joint
The center union nut draws the two halves together while allowing the fitting to be separated later without rotating the surrounding piping.
Threaded End
The opposite end connects to the adjoining piping component to create a serviceable threaded connection.
Construction Details
Midland Bronze Union Fittings are manufactured from high-quality domestic bronze to provide dependable mechanical strength, corrosion resistance, and long service life in compatible piping systems.
Each fitting uses a three-piece design consisting of two threaded union ends and a central union nut that securely joins the assembly.
This configuration allows piping sections to be disconnected for maintenance, inspection, repair, or equipment replacement without requiring adjacent piping to be cut or rotated.

What is a bronze union fitting used for?
A union joins two threaded piping sections while allowing them to be disconnected later without cutting or rotating the surrounding pipe.
What material are these unions made from?
They are manufactured from bronze.
Are these domestic fittings?
Yes. The supplied product information identifies these as domestic bronze fittings.
How is a union different from a coupling?
A standard coupling typically requires pipe rotation for removal, while a union can be separated at its center union nut.
Why is the three-piece design useful?
It allows the connected pipe sections to remain stationary while the union is opened for maintenance, inspection, or equipment replacement.
Where are unions commonly installed?
They are commonly used near valves, pumps, equipment, fixtures, and other locations where future servicing may be required.
Are multiple sizes available?
Yes. The supplied product information identifies multiple nominal pipe sizes.
Should thread sealant be used?
Use an appropriate thread sealant or PTFE tape on the threaded pipe connections according to the application requirements.
Can these be used in potable water systems?
The supplied product information identifies potable water and general plumbing applications.
What should I verify before ordering?
Confirm nominal pipe size, thread compatibility, pressure requirements, temperature, media compatibility, and installation conditions.
