How a Union Elbow Works
A union elbow changes the direction of a threaded piping system by 90 degrees while incorporating a union joint. The union nut can be loosened to separate the connection without rotating the attached piping. This makes the fitting useful near valves, pumps, equipment, and other components that may require periodic removal or service.
Common Applications

Frequently Asked Questions
What is a 300# black ductile iron union elbow used for?
It changes piping direction by 90 degrees while providing a union connection that can be separated for service or maintenance.
What connections does this union elbow have?
It uses female NPT threaded connections sized for the selected nominal pipe size.
How is a union elbow different from a standard elbow?
A standard elbow changes direction but normally requires the connected piping to be rotated during assembly or removal. A union elbow includes a union nut that allows the connection to be separated without rotating the adjoining pipe.
What pressure class is this fitting?
This fitting is manufactured as a 300# / Class 300 threaded ductile iron fitting.
What sizes are available?
Available product variations range from 1/2" through 2" nominal pipe size.
Should thread sealant be used during installation?
Use an approved pipe-thread sealant or thread tape selected for the piping media, pressure, temperature, applicable codes, and manufacturer recommendations.
Important Ordering Notes
- Select the required nominal pipe size before adding the product to your cart.
- This fitting combines a 90-degree elbow with a separable union connection.
- The selected variation determines the ASC item number, UPC, online selling price, weight, and net cost.
