A Stainless Steel (SS) Double Ferrule Equal Tee is a tube fitting meant to provide a T-shaped junction in tubing, in other words branch one inlet line into two outlet lines while maintaining the secure and leak-free connection.

Construction of SS Equal Tee

  1. Material: It is generally  made of stainless steel, which works best against  corrosion resistance and at the same time offers durability, and strength.
  2. Double Ferrule Design: Similar to other double ferrule fittings, the equal tee has two ferrules (compression rings) associated with each end. The front ferrule seals the connection against the fitting body, and the back ferrule provides support and grips onto the tubing.
  3. Tee Shape: The fitting is designed in a T-shape, allowing tubing to branch off at a 90-degree angle from the main line while maintaining the reliability of the connection.
  4. Body: The main body of the equal tee is made of stainless steel, ensuring stability and resistance to corrosion.
  5. Threads: The tee has UNF  external threads on all three ends, on which the tightening nut rotates compressing the double ferrule so that it bites the SS tubes and seals the joint.

Applications of SS Equal Tee

SS Double Ferrule Equal Tees are used in instrumentation lines where a T-shaped junction in tubing is required without compromising the integrity of the connection. Common applications include:

  1. Instrumentation Systems: Used in laboratories and industrial settings for precise control of fluid flow in instrumentation and control systems.
  2. Chemical Processing: Suitable for use in chemical processing plants where resistance to chemical corrosion is essential.
  3. Oil and Gas: Applied in hydraulic and pneumatic systems within the oil and gas industry for branching tubing in different directions.
  4. Power Generation: Used in power plants for fluid systems requiring T-shaped junctions.
  5. General Plumbing: Suitable for various plumbing applications where a T-shaped junction in tubing is needed.

Salient Features of SS Equal Tee

  1. Leak Resistance: The double ferrule design ensures a reliable and leak-tight seal, preventing fluid from escaping the connection.
  2. Pressure and Temperature Resistance: Stainless steel construction allows the equal tee to withstand high-pressure and high-temperature conditions.
  3. Corrosion Resistance: Stainless steel provides excellent resistance to corrosion, making these fittings suitable for use with corrosive fluids.
  4. Reusability: The design allows for multiple assembly and disassembly cycles without compromising the integrity of the connection.
  5. Easy Installation: Typically, these equal tees are easy to install, requiring simple tools for assembly.

When using SS Double Ferrule Equal Tees, it’s crucial to follow proper installation procedures, ensure compatibility with tubing and other components, and consider factors such as pressure, temperature, and the nature of the fluids being conveyed. Regular inspection and maintenance are also recommended to ensure the continued reliability of the connections.
