Henan Gnee New Material Co., Ltd. is one of the most reliable manufacturers and suppliers of aluminum pipe tee in China. With abundant experience, we warmly welcome you to wholesale high quality aluminum pipe tee in stock here from our factory. Good service and reasonable price are available.
GNEE is a manufacturer and supplier of aluminum tees - also called aluminum tee fittings - for piping and tubing systems. An aluminum tee creates a branch connection: it splits one flow path into two, or joins two flow paths into one, depending on the piping arrangement.
Available configurations include aluminum equal tees and aluminum reducing tees, with butt-weld, threaded and socket-weld connections where applicable. Aluminum tees can be supplied in different alloys, sizes, wall thicknesses and connection configurations according to the product design and customer requirements.
Applicable factory-made wrought aluminum and aluminum-alloy welding tees can be supplied according to ASTM B361, with dimensions according to ASME B16.9 where applicable. ASME B16.52 covers applicable forged nonferrous fittings with threaded and socket-welding ends, including aluminum and aluminum alloys.

Aluminum Tee Types
Aluminum tees are mainly classified by the relationship between the run diameter and the branch diameter.
|
Type |
Description |
Connection |
Applicable Standard |
|
Equal Aluminum Tee |
Run and branch have the same nominal size |
Butt Weld |
ASTM B361 / ASME B16.9 where applicable |
|
Reducing Aluminum Tee |
Branch has a smaller nominal size than the run |
Butt Weld |
ASTM B361 / ASME B16.9 where applicable |
|
Threaded Aluminum Tee |
Equal or reducing configuration with threaded ends |
NPT / BSP or specified thread |
ASME B16.52 where applicable |
|
Aluminum Socket-Weld Tee |
Equal or reducing configuration with socket-weld ends |
Socket Weld |
ASME B16.52 where applicable |
The applicable standard depends on the fitting type, manufacturing method and connection configuration. Confirm the standard before production.
Equal Aluminum Tee
An aluminum equal tee has the same nominal size at the run and the branch.
For example, a 2" × 2" × 2" aluminum tee has a 2-inch run and a 2-inch branch.
Equal tees are commonly used when a piping system needs to split one line into two branches of the same nominal size.
Typical applications:
Industrial piping
Compressed-air systems
HVAC systems
Equipment connections
Marine piping
Distribution manifolds
For applicable butt-weld fittings, dimensions should be selected for the specified size and configuration according to ASME B16.9.
Reducing Aluminum Tee
An aluminum reducing tee has a smaller branch diameter than the main run.
For example, a 4" × 4" × 2" reducing aluminum tee has a 4-inch run and a 2-inch branch.
A reducing tee creates a branch connection without the need for a separate reducer and tee in some piping layouts.
Typical applications:
Process piping
Equipment branches
Instrument connections
HVAC distribution
Compressed-air systems
Marine piping
Available reducing combinations depend on the applicable fitting dimensions, manufacturing process and customer requirements.
Aluminum Tee Connection Types
The right connection type depends on the installation method and the existing piping system.
Butt-Weld Aluminum Tee
A butt-weld aluminum tee is joined to the pipe by welding. The pipe and fitting ends are aligned and welded together. This connection is used for permanent piping assemblies.
Applicable factory-made wrought aluminum and aluminum-alloy welding fittings can be supplied according to ASTM B361, with dimensions according to ASME B16.9 where applicable.
Typical uses:
Industrial piping
Compressed-air systems
Marine piping
Equipment connections
Threaded Aluminum Tee
A threaded aluminum tee uses threaded ends to connect compatible pipes, fittings, valves or other components.
Common thread requirements:
NPT
BSPT
BSPP
Metric threads where specified
NPT and BSP are different thread systems and should not be treated as interchangeable. Specify the thread type and size when requesting a quotation.
Applicable forged aluminum and aluminum-alloy threaded fittings can be supplied according to ASME B16.52, which covers dimensions, tolerances, ratings, marking and material requirements.
Socket-Weld Aluminum Tee
A socket-weld aluminum tee has socket ends. The mating pipe or tube is inserted into the socket, then welded.
This connection is commonly considered for small-bore piping where a socket-weld configuration is appropriate.
Applicable forged aluminum and aluminum-alloy socket-welding fittings can be supplied according to ASME B16.52. Confirm the socket dimensions, pipe size, alloy and wall thickness before production.
Aluminum Tee Dimensions
For butt-welding tees, dimensional requirements should be established according to the applicable ASME B16.9 configuration.
ASME B16.9-2024 covers factory-made wrought butt-welding fittings from NPS 1/2 through NPS 48 (DN15 through DN1200) and includes dimensions, tolerances, ratings, testing and marking requirements.

Note: These values are standard dimensional references from ASME B16.9 for the equal butt-weld tee. They are not a guarantee of GNEE stock for every alloy or wall thickness.
For reducing tees, dimensions vary with the run and branch combination and should be confirmed for the specific size pair. For custom aluminum tees, GNEE can work from a customer drawing or an agreed specification.

About Pipe Schedule
Where the tee matches compatible pipe dimensions, customers can specify pipe schedules such as SCH10, SCH40, SCH80 or SCH160.
Pipe schedule is not a standalone pressure rating for an aluminum tee. The actual pressure capability depends on:
Aluminum alloy
Temper
Wall thickness
Tee geometry
Fitting size
Operating temperature
Connection method
Applicable design code
Service conditions
GNEE recommends confirming the complete fitting specification before assigning a pressure rating.

Applications of Aluminum Tee
Industrial Piping
Aluminum tees can create branch connections in compatible industrial piping systems, equipment connections and distribution lines.
Compressed Air
Tees can divide compressed-air flow between the main distribution line and branch lines. Aluminum systems are often chosen where lightweight installation and corrosion resistance are important.
HVAC and Air Handling
Aluminum tees can create branch connections in compatible HVAC and air-handling systems.
Marine Piping
Aluminum alloys such as 5083 and 5086 can be considered for suitable marine applications where corrosion resistance, low weight and weldability are required. Confirm the alloy and temper according to the marine project specification.
Instrumentation
Small-bore threaded or socket-weld tees may be used for selected gauge, sensor and instrument connections. Confirm the thread type, pressure requirements and material compatibility before installation.
Equipment Connections
Aluminum tees can be used around compatible pumps, valves, manifolds, heat exchangers, tanks and process equipment.
