What Is a Pipe Fitting?

Pipe fittings are responsible for connecting and securing various sections of pipes within a plumbing system. These components help build an efficient network that can be utilized to distribute water, gas, and other fluids in your house.

Pipe fittings are designed to perform various functions, such as changing the flow direction, regulating the speed, and sealing off a pipeline. Also, they come in various shapes, sizes, and materials. You can find copper, iron, plastic, and steel pipe fittings. Lastly, each type of pipe fitting caters to your different requirements and preferences.

Standard Names of Pipe Fittings

Pipe fittings come in different shapes and sizes. Some pipe fittings you will find include elbow shape, adapters, values, and expansion joints. The pipe fitting you use when building a pipe system will depend on your needs. So, how do you know which pipe fitting you will need for the job? Below we will go over ten common pipe fittings to help you decide.

1. Gaskets

Gaskets are pretty distinguishable due to their shape, feature, and material. These pipe fittings are shaped like a ring and are used to seal flange joints. Depending on your flange, you will use a specific gasket material for the task. For example, a nonmetallic spiraled gasket is used for raised-face flanges. Also, you will use the ring-shaped gaskets for ring-type flanges.

2. Pipe Elbows

Pipe elbows help direct the flow of the plumbing system in the direction you want it to go. It comes in various degrees, but the most common is the 90-degree and 45-degree elbows. Also, pipe elbows come in two types including long radius( 1.5D) and short radius (1D).

The 90-degree elbows tilt the flow of the plumbing system into a 90-degree angle. It is available in long-radius and short-radius types. The 45-degree elbows shift the system to a 45-degree angle and are only available in the short radius type. Long-radius elbows are used to provide less pressure on the plumbing system.

However, you must ensure you have room to use this pipe fitting. If you don't, you will use a short radius elbow for the task as it takes less space. However, it does have a high-pressure drop due to the fast change in the flow direction.

3. Pipe Bend

Pipe bends are long radius fittings used in systems requiring pigging. This type of pipe connector provides a low-pressure flow due to the seamless change in the flow of directions it gives. Pipe bends come in two dimensions including 3D and 5D.

4. Pipe Tee

A pipe tee collects the fluid running from the main pipeline. It has a 90-degree branch and is located in a small pipeline area. There are several types of pipe tees including straight tees, reducing tees, barred tees, and wye tees. The straight tee has the same diameter as the main pipe, while the reducing tee has a smaller diameter.

Barred tees are used in piggable pipelines, and a worker welds a restriction bar across to prevent items from entering. However, water, gas, and other liquids can flow freely through the bars. Lastly, the wye tee is used to connect two pipes at a 45-degree angle. Its job is to lower the friction and turbulence of the piping system.

5. Cross

A cross is a four-way pipe fitting with one inlet and three exits. It's mainly used for fire water sprinklers, not for transferring fluids in a plumbing system.

6. Pipe Reducers

A pipe reducer helps decrease the diameter of a pipe. There are two different types: concentric and eccentric. Concentric pipe reducers help maintain the center elevation of a pipeline. They are used when two different pipe sizes must be made the same at the center of a system. Eccentric pipe reducers help keep the bottom of a pipe at a certain level. Its job is to keep the pipe system exterior surface at a constant level throughout.

7. Pipe Caps

At the end of the plumbing system is a cap. A pipe cap covers the dead end of a plumbing system to prevent leakage.

8. Stub Ends

Stub ends have the same function as pipe caps. However, they are used for lap joint flanges.

9. Piping Unions

Piping unions are used for low-pressure pipes that are frequently dismantled. This type of pipe fitting has three parts including a female end, male end, and a nut. The nut is used to create a strong seal along with the female and male ends.

10. Pipe Coupling

There are three different types of pipe couplings: full coupling, half coupling, and reducing coupling. A full coupling is used for connecting tiny bore pipes. Half coupling fittings branch a small bore pipe to a large one. Lastly, a reducing coupling is to connect two pipes with different diameters.

5 Water Line Leak Symptoms

Over time your pipes can corrode and lose their connection to the main water line. Unfortunately, when this happens, so will water leaks. So, you need to know the signs of a water line leak, which we will show you in this section.

1. Water Puddles

If it hasn't rained lately and you see water puddles in your yard, it's coming from a water leak. Usually, it will happen around your kitchen sink. So, check to make sure there is nothing wrong with it.However, large water puddles that move toward the street indicate a main water line leaking. Sometimes water puddles are not obvious, and you will only notice wet grass. So keep this in mind when looking for puddles.

2. Low Water Pressure

Low water pressure is another sign that there is a leakage in your house. Sometimes you may notice a change of pressure only in the shower. This could be due to sediment build-up. However, if you see a difference throughout the house in the water pressure, it could be significant. It's best to contact a plumber quickly to fix the problem.

3. Hissing Sounds

You will hear a hissing noise within the walls and floors when a pipe bursts. Sometimes the noise is low and has more of a bubbling sound. However, either sound is not a good sign.

4. Frequent Clogs

Clogs often happen in homes and usually there is nothing to worry about. However, if a clog becomes a more common problem, it could be due to water leakage.

5. Discolored Water

When the main water line breaks and begins to flow into the environment, dirt and other particles find their way into the water. This is when you will start noticing a change of color in your water supply.

A Guide To Pipe Fittings and How To Use Them

I doubt there's a DIY plumber out there who hasn't experienced the frustration making multiple trips to the hardware store to complete a repair. I know I have.

Putting together a network of pipes of different diameters and materials can be like assembling a puzzle. Sometimes you don't know exactly which fitting to buy until you reach the part of the puzzle where you need it.

Plumbing fittings vary by size, purpose and material. You often must tie together pipes of different materials with transition fittings. The materials in common use today ' copper, PVC and CPVC, PEX, ABS, galvanized steel and cast iron ' can mostly all be connected to each other with appropriate fittings.

With all the different pipe sizes and materials out there, things can get confusing. Fittings for water lines are different than those for drain and waste lines. It's no wonder professional plumbers don't go anywhere without a truck full of fittings. It's their magic cupboard, letting them complete installations and repairs much more efficiently than amateurs like me.

Water Line Fittings

PEX is quickly becoming the material of choice for water lines. But PVC, CPVC and copper are still in common use, as is galvanized steel outdoors.

Three reasons for PEX's popularity are its flexibility (it can bend around corners), durability and ease of assembly. You simply push PEX pipes and fittings together rather than gluing (PVC and CPVC), soldering (copper) or screwing them (galvanized steel).

Here are the fittings you're most likely to need when assembling or repairing water lines:

  • Coupler: Joins two lengths of pipe in a straight line. Whenever you cut a pipe during a repair, you'll need a coupler to put it back together.
  • Bend: For changing pipe direction. The most common bend angles are 90 degrees (aka elbows) and 45 degrees. Bends are typically made of the same material as the pipe except for PEX bends, which are brass or hard plastic.
  • Tee: Shaped like the letter 'T' with two parallel ports and a perpendicular one. It's used for adding a branch line. When the branch line is a different size than the main one, you can make the connection with a reducing tee.
  • Reducing adapter: Another way to join pipes of different diameters. It may be shaped like a bell (common for copper and galvanized pipes) or fit inside the larger pipe (more common for plastic). The first type is a bell adapter, and the second a reducing bushing.
  • Union: A type of coupler you can take apart. Its large threaded nut holds together the two halves of the connected pipe. You can use one in place of a coupler in any situation where you temporarily disassemble the pipes.
  • Threaded adapter: To join a pipe with a glue or solder slip joint to one with threads, you'll need a threaded adapter. It can have male or female threads. Threaded adapters join plastic pipes to each other, or copper to itself or to brass.
  • Compression fitting: This lets you join plastic or copper pipes without glue or solder. Most feature a ring that fits around the pipe and a nut that tightens onto the fitting, wedging the ring into the gap between the pipe and fitting. Compression fittings allow for easy pipe repair. Most modern faucet and toilet shutoff valves have compression fittings.

Waste and Drain Fittings

Cast iron was a common material for drain pipes in the first part of the 20th century. They're usually connected with couplers that feature rubber gaskets surrounded by stainless steel sheathing.

These days, most drains are made with PVC or ABS plastic. Plastic drain fittings are usually glued, but the ones you might need to remove temporarily, like cleanout plugs, are threaded.

Here are the most common drain fittings. The list doesn't include couplers and ordinary bends, because they're similar to the ones used for water pipes and serve the same purposes.

  • Long-sweep elbow: Makes a 90-degree bend in a longer arc than an ordinary elbow to allow water to flow more smoothly. It's used for connecting vertical drain lines to horizontal ones.
  • Straight tee: Performs the same function as tees for water lines, but are seldom used for drain lines. They're mostly for vents, tying horizontal pipes to vertical stacks.
  • Sanitary tee: Aka a santee, this has a sweep on its perpendicular port to promote water flow in the direction of the sweep. Use it to connect a horizontal waste line to a vertical one, but not a vertical one to a horizontal one. That's the job of the next fitting.
  • Wye: Shaped like the letter 'Y,' a wye does the same job as a sanitary tee, but with less chance of backflow. This is the fitting you need to connect the vertical drain from your sink or toilet to the sewer. You can also use it to connect a horizontal waste pipe to a vertical one.
  • Double wye: As you might expect, this has two inlet ports instead of just one. It's commonly used for connecting a double-basin sink to a single P-trap.

Transition Fittings

Whether you're connecting PVC or CPVC pipes to copper, cast iron pipes to ABS or galvanized pipes to copper, you'll need a transition fitting. In some cases, you can do it by taking two threaded adapters of different materials and screwing them together. But it's often easier to use an adapter specifically made to couple them, assuming you can find one.

  • Plastic-to-copper slip adapter: This fitting has male copper threads on one end and a PVC or CPVC slip joint on the other. After soldering a female thread adapter to the copper pipe, you screw in the adapter and glue the plastic pipe to the slip joint.
  • Dielectric union: Used for mating copper or brass to galvanized steel, its insulating washer keeps the pipes electrostatically separated to prevent corrosion. Dielectric unions are commonly used when installing water heaters.
  • Cast iron to plastic coupling: These are widely known as Fernco couplings after the company that makes most of them. They consist of a rubber cylinder surrounded by a stainless steel sheath and two or more threaded pipe clamps tightened with a screwdriver.
