Female Tee Fitting

Female Tee Fitting

The SIYelectric Stainless Steel Female Tee Fitting is designed to create a secure three-way connection in tubing, piping, instrumentation, and process systems.

With female threaded ports, this tee fitting allows three male-threaded pipes, valves, instruments, or fittings to be connected at one point. It is commonly used when a pipeline needs to be branched, combined, or connected to an additional instrument port.

Manufactured from stainless steel, the fitting provides good mechanical strength, corrosion resistance, and sealing reliability in demanding industrial environments. It is suitable for fluid, gas, water, oil, chemical, hydraulic, pneumatic, and instrumentation applications.

Key Functions

Three-Way Female Thread Connection

The female tee fitting connects three male-threaded components in one compact structure. It can be used to create a branch line, combine flow paths, or add an instrument connection point.

Secure Sealing and Easy Installation

The threaded design supports convenient installation and disassembly. With proper thread standard, sealing material, and tightening method, it helps provide stable and leak-resistant operation.

Compact Piping Layout

The tee structure reduces the need for multiple separate fittings and helps simplify the layout of instrument panels, process skids, and pipeline systems.

Compatible Instruments and Components

This female tee fitting can be used with:

• Pressure transmitters
• Differential pressure transmitter impulse lines
• Pressure gauges
• Pressure switches
• Gauge valves and needle valves
• Instrument manifolds
• Calibration and test ports
• Sampling lines and analyzer systems
• Hydraulic and pneumatic control panels

For pressure transmitter or gauge installation, the female tee fitting can provide an additional branch connection for testing, venting, calibration, or local pressure indication.

Typical Applications

Instrument Tubing and Pressure Measurement Lines

Used in pressure measurement points where one process connection needs to support a pressure gauge, pressure transmitter, test port, or valve connection.

Sampling and Analyzer Systems

Suitable for gas sampling lines, liquid sampling systems, analyzer panels, and laboratory test setups where a compact branch connection is required.

Hydraulic and Pneumatic Control Lines

Used in hydraulic power units, pneumatic panels, actuator control lines, and equipment assemblies where multiple threaded connections need to meet at one point.

Process Skids and Equipment Panels

Applied in compact process skids, dosing systems, filtration equipment, test benches, and control panels where space-saving three-way connection is needed.

Chemical and Industrial Fluid Systems

Suitable for compatible chemicals, water, oil, gas, and other industrial fluids. Material, thread type, sealing method, and pressure rating should be selected according to the actual medium and operating conditions.
