Different Types of Pipe Fittings and Their Uses

A pipe fitting is a piping part used to connect branches, change pipe sizes, or alter a pipe’s direction. fittings, such as elbows, reducers, tee connections, caps, and crosses, are widely used in the piping and plumbing industries. Pipe fittings are essential for the efficient operation of pipes and tubes in a variety of applications.

Types of Pipe Fittings


When two pipes are connected, elbows are used to alter the direction of flow. The most common angles for elbows are 22.5 degrees, 45 degrees, and 90 degrees. Elbow pipe fittings are only used if the pipes have the same diameter, then conventional elbows are implemented. Different materials are used to create elbows, which often come with female threads that can be connected by butt welding or socket welding.


A T-shaped fitting is a type of plumbing fitting that has one input and two outputs positioned at a 90-degree angle to the main line attachment (input). It can also be used to combine the flow from two inputs to one outlet. Different varieties of these fittings come in various materials and sizes. If all three sides of the T-fitting measure the same length, it is known as an Equal tee; if the sides are not of the same measurement, it is an Unequal tee.


Cross-type connectors have four ports in four directions. This interface occurs when four tubes meet at a single point. As the temperature varies, these connections generate higher amounts of pressure exerted on the piping due to their location at the core of the four junctions. Cross fittings are commonly used for fire protection sprinkler systems.

Pipe Cap fittings:-

A cap is a type of pipe fitting that performs the same function as a plug, except that the plug has male threads, while the cap has female threads which are screwed into the male thread. There are various materials available for these, such as rubber, steel, copper, and plastic.

  • Reducers:-

A reducer is a pipe-fitting component that reduces pipe size, thereby reducing flow size. However, there are two types of reducers available. I.e concentric & eccentric.

The concentric reducer is cone-shaped with gradual decreasing around the pipe but in this case accumulation of air may be possible and it results in cavitation. Another one is the eccentric reducer which has one edge parallel to the connecting pipe due to which air accumulation is not possible.

  • Couplings:-

Coupling pipe fittings are used to connect pipes of the same diameter, Couplings are also useful if the pipe is broken or leakage occurs. In general, there are two types of couplings. I.e Compression Coupling and Slip Coupling:

Compression coupling –  A compression coupling is a type of regular coupling connected between two pipes. It prevents leakage by arranging gaskets or rubber seals on both sides, or with glue if none is available.

Slip coupling – Slip coupling is easier to install and it contains two pipes that are arranged as one into another, the inner pipe can slide up to some length. So, we can fix long-length damaged pipes by slip coupling.

Uses of Pipe Fittings

There is no end to the use of pipe fittings. The list of applications for piping fittings continues to grow, but its strength, flexibility, high flow rates, and chemical resistance make it uniquely suited to the movement and transfer of liquids, steam, solids, and air. With pipe fitting, there are many uses such as:

  • Chemicals and wastes are extremely hazardous to transport.
  • Protecting sensitive equipment from high pressures.
  • Corrosion and extreme weather protection.
  • Household and industrial chemicals are resistant to it.

Considering Various Purposes Pipe Fittings are Used in Various Industries

  • Chemical / Petrochemical
  • Municipal
  • Food, Beverage, and Dairy
  • Oil and Gas
  • Power
  • Process Instrumentation
