Description
150# Black Malleable Side Outlet Tee
150# Black Malleable Side Outlet Tees provide a four-way threaded branch connection for piping systems where one straight-through run and two branch outlets are required. Manufactured from black malleable iron, these fittings are commonly used in industrial, mechanical, air, gas, water, and general-purpose threaded piping applications.
The side outlet tee configuration combines the function of a standard tee with an additional side branch, allowing multiple piping directions to be connected from a single fitting. Female NPT threaded ends provide convenient assembly with compatible threaded pipe, nipples, valves, and fittings.

Construction Details
These side outlet tees are manufactured from malleable iron, providing a durable threaded fitting for common industrial and mechanical piping applications.
The black finish is commonly used in mechanical, industrial, compressed-air, compatible gas, and general-purpose piping systems where a galvanized coating is not required.
The fitting incorporates four female threaded openings: two opposing run connections, one standard tee branch, and one additional side outlet positioned perpendicular to the other connections.
Side Outlet Tee Configuration
Straight Run
Two opposing threaded openings create the primary straight-through piping run.
Tee Branch
A third threaded opening branches from the main run in the same manner as a conventional threaded tee.
Side Outlet
A fourth threaded opening provides an additional branch connection, allowing piping to extend in another direction from the same fitting.
Why Use a Side Outlet Tee?
Multiple Connections in One Fitting
- Creates four threaded connection points
- Reduces the need to combine multiple tees and nipples
- Helps simplify compact piping layouts
- Useful where several branches originate from one location
- Supports cleaner mechanical piping assemblies
Threaded Installation
- No welding required
- Compatible with appropriately sized threaded pipe
- Easy to assemble with standard pipe tools
- Serviceable threaded connection
- Suitable for field installation and maintenance
Common Applications

- Maintenance and repair systems
Utility & General Service
- Compatible gas piping
- Compatible water piping
- Utility piping
- Shop piping systems
- General threaded service
How a Side Outlet Tee Works
A side outlet tee combines four threaded ports into a single compact fitting. Two ports form the main piping run, while the remaining two ports provide branch connections in different directions.
This configuration can simplify piping arrangements that would otherwise require a combination of standard tees, nipples, elbows, or additional fittings.
Each female NPT connection receives a compatible male threaded pipe, nipple, valve, or fitting. Appropriate thread sealant or PTFE thread sealing tape should be selected for the piping material and intended service.
Threaded Connection Considerations
- Confirm the required nominal pipe size before ordering.
- Use compatible male NPT threaded pipe or fittings.
- Inspect male and female threads for damage before assembly.
- Clean dirt, scale, oil, and debris from the threads.
- Apply an appropriate thread sealant or thread sealing tape.
- Start connections by hand to reduce the risk of cross-threading.
- Use appropriate pipe wrenches or fitting tools for final assembly.
- Avoid excessive tightening that could damage the fitting or adjoining components.
- Properly support adjoining piping so excessive mechanical loads are not transferred to the fitting.
- Test completed piping connections according to applicable system requirements before service.
Black Malleable Iron Construction
Malleable iron fittings are commonly used in threaded piping systems because they combine mechanical strength with the ability to accommodate stresses encountered during assembly and service.
The black finish is commonly selected for indoor mechanical systems, industrial piping, compressed air, compatible gas service, and other applications where black malleable iron fittings are appropriate.
Material suitability should always be confirmed for the intended process fluid, environmental exposure, operating temperature, pressure, and applicable piping requirements.
Product Selection Considerations
Pipe Size & Layout
Confirm the nominal pipe size of all four connections and verify that the side outlet tee configuration matches the required piping layout before ordering.
Service Conditions
Verify that black malleable iron, threaded NPT connections, and the 150# fitting class are appropriate for the process media, operating pressure, temperature, environment, and applicable system requirements.

Frequently Asked Questions
What is a side outlet tee?
A side outlet tee is a four-opening fitting with two opposing run connections, a standard tee branch, and an additional side branch positioned perpendicular to the other outlets.
What material is this fitting made from?
This fitting is manufactured from black malleable iron.
What does 150# mean?
150# identifies the fitting pressure class. Actual allowable pressure depends on fitting size, operating temperature, piping material, system design, and applicable standards.
What type of connections does the fitting have?
The side outlet tee uses female NPT threaded connections designed to mate with compatible male threaded pipe and fittings.
How many openings does a side outlet tee have?
A side outlet tee has four openings: two for the straight run, one standard branch, and one additional side outlet.
Why use a side outlet tee instead of several fittings?
A side outlet tee creates multiple piping directions from one compact fitting, potentially reducing the number of tees, elbows, nipples, and other fittings required in the piping layout.
Does this fitting require welding?
No. It is a threaded fitting and is assembled using compatible male NPT threaded piping components.
Should thread sealant be used?
An appropriate pipe thread sealant or PTFE thread sealing tape should be selected according to the piping material, process media, pressure, temperature, and applicable installation requirements.
Can this fitting be used for gas?
Black malleable iron fittings are commonly used in compatible gas piping systems, but suitability must be verified for the specific gas service, pressure, temperature, piping code, and local requirements.
How should the completed piping connection be tested?
The completed piping system should be tested using the procedure required by the applicable piping code, project specification, and service before being placed into operation.
