Tube Fittings

Tube Fittings


A fitting is a part of a pipe or tube which helps in connecting it to another component. These fittings are widely used in various mechanical and plumbing operations for a wide range of applications. They can be available in a wide range of shapes and sizes which are produced from different types of material.

Tube fittings are devices that connect tubes to other tubes or related material. The most common amongst them are elbows, tees, flanges, unions, coupling, stub ends, etc. These fittings have considerable strength and can withstand different temperatures depending on the material used to produce them.

The range of products are produced using metal or steel material. The fitting and the tube are configured in such a direction that is completely sealed. This enables the smooth flow of fluids and gases without any leakage. An industrial module possesses a working pressure of up to 9200 psig while a stainless steel element exhibits 12,100 psig of working pressure.

How to use?

A tube is a hollow structure that allows for a smooth flow of fluids and gases. Made from rolled or extruded metal these fittings cannot be threaded on the end to form a connection. A component known as tube fitting has to be utilized to couple the element to other structures. They cannot be utilized for transmitting high-pressure loads as they are thin-walled. This infers that they have to be utilized for small-diameter systems. Since they can be easily cut they are llabor-intensive and can be cut easily and joint with different connectors.

A compression fitting is the most common module used to fit different tubes. They consist of a ferrule, nut, and body of the element. They together tighten and ensure a metal-to-metal seal.

What is ferrule fittings?

A ferrule is a fitting which is produced utilizing different types of material. They are utilized for joining different sections of tubes together. It is made up of a circular clamp that connects different wires, fibers, or posts in a system. These components made up of rings that are used to reinforce a shaft or bind the strands of material together. They provide protection against damage caused due to splitting and wear.


Tube fittings are used in industrial and domestic applications. They act as means to facilitate the flow of fluids and gases. In the piping industry, they can be used to seal the ends of different components. These components can also be used to stop or increase the flow characteristics of different elements. They help to increase the overall functionality of the entire system.

What are the two parts of a flared tube fitting?

Flare tubing belongs to the category of compression fitting. They are utilized with metal tubing which, is usually made up of soft steel, aluminium, and ductile copper. This process is mostly carried out during the cold rolling process. It is made up of two parts namely a sleeve and a nut. The nut is fitted over the sleeve and tightened. They are tightly flared against the male fitting which, enables it to form a tight seal.

How do I choose a tube fitting?

Fittings in this grade are produced using different materials and are available in different sizes. Choosing the correct module is essential to prevent leaks, unwanted restrictions, and extra costs.
Some common points to consider while selecting the component.

  • Select the correct components and clean them before installing.
  • Tighten without damaging any other elements.
  • Evaluate the material used in the tubing.
  • Check the compatibility of both modules.
  • Check the optimum working pressure and temperature conditions of the system.

Why do flare fittings leak?

Flare fittings leak due to some basic mistakes and errors that incur during the initial fitting process. A bad flare, burrs on the tube, wrong size of the flare may be some reasons for the undue leakage. However, the most common reason is due to overtightening them and using faulty nuts for fitting them.

How much does it cost to tighten a flare fitting?

The tightening process in flare fitting depends on the size and the material used in the entire system. The different methods utilized in fitting them also decide the overall price of the fitting.
