Stainless Steel Male Connectors Tube Fittings

Stainless Steel Male Connectors Tube Fittings Product Overview

SIYelectric Stainless Steel Male Connectors Tube Fittings are used to connect tubing to female-threaded ports in instrumentation, hydraulic, pneumatic, gas, and process piping systems.

One side of the connector is designed for tube connection, while the other side uses a male threaded connection to match valves, manifolds, instruments, equipment ports, or process pipelines. This structure provides a practical transition from tube lines to threaded components and is commonly used in compact industrial systems where reliable sealing, pressure resistance, and easy maintenance are required.

With stainless steel construction, these male connectors are suitable for demanding environments involving pressure, temperature changes, vibration, moisture, and compatible corrosive media.

Where This Fitting Is Used

1. Instrument Tubing Connections

Used to connect tubing lines to pressure instruments, valves, manifolds, and test points in industrial measurement systems.

Typical use points include:

• Pressure transmitter impulse lines
• Differential pressure transmitter tubing
• Pressure gauge connections
• Calibration ports
• Test lines
• Sampling points

2. Pressure Transmitter and Gauge Installations

These male connector tube fittings are suitable for connecting tubing to:

• Pressure transmitters
• Differential pressure transmitters
• Pressure gauges
• Pressure switches
• Gauge valves
• Needle valves
• Instrument manifolds
• Analyzer panels

For transmitter installations, the male connector helps connect the instrument tubing to a manifold, valve, or process connection with a female-threaded port.

3. Hydraulic and Pneumatic Systems

In hydraulic and pneumatic systems, stainless steel male connectors are used to connect control lines, actuator lines, pressure lines, and equipment ports.

They are suitable for:

• Hydraulic power units
• Pneumatic control panels
• Air supply systems
• Actuator control circuits
• Pressure test equipment
• Compact machinery assemblies

4. Sampling and Analyzer Systems

Male connectors are also widely used in sampling systems and analyzer panels where small tubing must be connected securely to valves, filters, regulators, or instruments.

Common applications include:

• Gas sampling lines
• Liquid sampling systems
• Analyzer cabinets
• Laboratory test systems
• Process monitoring skids

5. Process Skids and Industrial Piping

For process skids and industrial equipment, male connectors provide a compact and reliable tube-to-thread connection.

They can be used in:

• Chemical dosing skids
• Filtration units
• Gas panels
• Water treatment equipment
• Utility lines
• General fluid and gas transfer systems

Key Benefits

Selection Notes

When selecting stainless steel male connectors, the following details should be confirmed:

• Tube outer diameter
• Thread type, such as NPT, BSP, BSPT, or metric thread
• Material grade, such as SS304 or SS316
• Working pressure
• Working temperature
• Process medium
• Required sealing method
• Whether the fitting is used for instrument tubing, hydraulic tubing, or process piping

For corrosive media, high-pressure service, or high-temperature applications, material compatibility and pressure rating should be checked before selection.
