A fitting or adapter is used in pipe systems to connect straight sections of pipe or tube, adapt to different sizes or shapes, and for other purposes such as regulating (or measuring) fluid flow.

How do I identify a pipe fitting?

For male pipe threads, be sure to measure the outside diameter at the widest point of the threads. For female pipe threads, measure the inside diameter at the widest point of the threads. You can then use these measurements to find the right size in a nominal pipe size conversion chart .

What are the 4 types of fittings?





Types of Pipe Fittings in Plumbing System

  • Elbow.
  • Reducer.
  • Tee type.
  • Cross type.
  • Coupling.
  • Unions.
  • Adaptors.
  • Olet.

What is the name of pipe fitting?

When two ends of pipes are joined, the pipe fitting used is called union. A union is made of three parts namely a nut, a male end and a female end.

How do you read plumbing fittings?


Quote from Youtube video: And basically what that means is that the threads taper in you can see it's just very slightly on this fitting here and what that basically means is that when you thread this in it compresses.

How do you tell what size an fitting I have?

You can always identify AN fittings based on the male thread size (outside diameter). These sizes are constant regardless of brand, hose type, or fitting configuration. If your fitting has a convex 37 degree flare at the end, the threads will tell you the AN size (and vice-versa).

What is an fitting size?

What is pipe and pipe fitting?

Pipe Fittings are defined as the piping components that help in pipe routing for directional changes, size changes, and branch connections. Piping Elbows, Piping Reducers, Tee Connections, Olet Connections, Caps, Crosses, etc are pipe fittings and widely used in both the piping and plumbing industry.

What is the types of fitting?

There are many different kinds of fittings, made from a variety of materials: some of the most common types are elbows, tees, wyes, crosses, couplings, unions, compression fittings, caps, plugs and valves.

What are plumbing materials?

Today, most plumbing supply pipe is made out of steel, copper, and plastic; most waste (also known as “soil”) out of steel, copper, plastic, and cast iron. The straight sections of plumbing systems are called “pipes” or “tubes”.

How many types of pipe fittings are there?



Coupling, Adapter, Bushing and Union Fittings



A coupling can be a reducer, or reducing coupling, meaning they reduce flow by joining a larger pipe to a smaller size. Adapters are used when connecting two pipes of different types.

What is the difference between joints and fittings?

Pipes are connected with the help of joints. A variety of joints are used in an assembly of pipes. Connecting two or more pipes together is called a fitting. Various types of joints could be used in a pipe as per the requirement.

What is pipe socket?

A socket is a fitting that simply goes over the end of a pipe. A 1″ socket end will fit on a 1″ pipe. These are extremely common. Many PVC couplings have socketed ends. A commonly used abbreviation for “socket” is “soc.”

What are PVC fittings?



These fittings are designed to change the end type of a pipe, allowing it to connect to fittings and pipes of many sizes. They can have threaded or slip socket ends to connect to an endless variety of pipes and fittings.

What is a threaded fitting?

Threaded joints probably represent the oldest method of joining piping systems. Like Socket Weld fittings, threaded fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller.

What are weld fittings?

Welded pipe fittings in carbon steel and stainless steel are the joining components that make possible the assembly of valves, pipes and equipment onto the piping system. Welded fittings compliment pipe flanges in any piping system and allows; Change direction of flow in a piping system.

What is the difference between socket and pipe?

A socket is a part of the OSI model that enables communication between different layers. Pipes are used in processing in the CPU. Communication in socket is bi directional while it’s unidirectional in pipes. Pipes increase productivity By processing multiple processes simultaneously.

What is seamless pipe?



Seamless pipes are derived from solid steel that is in sheet or bar form and is formed into a solid round shape known as “billets” which are then heated and cast over a form such as a piercing rod to create a hollow tube or shell.

What are steel fittings?

Steel pipes and pipe fittings are widely used in houses and industrial purposes for carrying water, flammable gases, fire sprinkler systems, etc. As steel pipes tend to rust, they are often mixed with other materials to add to its durability and make it rust resistant.

What are forged pipe fittings?

Forged fittings are constructed of A105 (carbon steel), nickel or stainless steel alloy. Such fittings are stronger and thicker and are built for heavy industrial use. Forged Iron Pipe Fittings are available in pressure groups 2000 #, 3000 #, 6000 #, and 9000#.

What are galvanized fittings?

What are galvanized pipes? Galvanized pipes are steel pipes that have been dipped in a protective zinc coating to prevent corrosion and rust. Galvanized piping was commonly installed in homes built before 1960. When it was invented, galvanized pipe was an alternative to lead pipe for water supply lines.
