Description
150# Black Malleable Side Outlet Tees
150# Black Malleable Side Outlet Tees provide a compact four-way threaded connection for piping systems requiring a straight run with two branch outlets. The side outlet configuration helps create multiple piping directions from a single fitting while maintaining threaded connections throughout the assembly.
Designed for use with compatible threaded pipe and components, these black malleable iron fittings are well suited for industrial, mechanical, utility, and general-purpose piping installations where a side outlet tee configuration is required.

Construction Details
These side outlet tees are constructed from black malleable iron for use in compatible threaded piping systems.
The fitting incorporates four threaded openings. Two opposing connections form the primary straight-through run, while a standard tee branch and an additional side outlet provide two additional piping directions from the same fitting.
The compact four-opening configuration can simplify piping layouts that would otherwise require multiple individual fittings and short pipe nipples to achieve similar branch connections.
Available Side Outlet Tee Sizes
Side Outlet Tee Configuration
Straight Run
Two opposing female threaded connections create the primary straight-through piping run.
Tee Branch
The standard tee branch provides a perpendicular connection from the primary piping run.
Side Outlet
An additional side outlet creates a fourth connection point for another piping direction from the same fitting.

- Industrial piping layouts
- Compressed air systems where compatible
- Equipment connections
- Maintenance and repair piping
General Piping
- Utility piping
- Shop piping systems
- Compatible gas service
- Compatible water service
- General threaded piping installations
Threaded Connection Considerations
- Confirm the required nominal pipe size before ordering.
- Use compatible male threaded pipe, nipples, valves, or fittings.
- Inspect male and female threads before assembly.
- Remove dirt, scale, oil, and other debris from the threads.
- Select a pipe thread sealant suitable for the intended piping service.
- Begin threaded connections carefully to help prevent cross-threading.
- Use appropriate installation tools during final assembly.
- Avoid excessive tightening that could damage the fitting or adjoining components.
- Support adjoining piping to minimize unnecessary mechanical loading on the fitting.
- Verify the completed system according to applicable project and piping requirements before operation.
Product Selection Considerations
Size & Configuration
Confirm the required nominal pipe size and make sure the four-opening side outlet tee configuration matches the intended piping layout before ordering.
System Requirements
Confirm that black malleable iron, the 150# fitting class, threaded connections, and the selected fitting size are appropriate for the intended process media, temperature, pressure, environment, and piping system.
