Polyvinyl chloride (PVC) pipe fittings are used to connect together two pieces of PVC pipe.

They are largely used around the home and commercial buildings for purposes such as transporting water around the home, garden and lawn. They are ideally suited for transporting the main water supply of a home or building to where it needs to go.

PVC pipe fittings are also suitable for the distribution of air – both high and low pressure.

Types and Sizes

Like all types of pipe fittings, PVC pipe fittings come in a variety of types and sizes to suit varying needs. PVC pipe fittings most commonly come in sizes ranging between 0.5 up to 4 inches in diameter.

The most common types of PVC pipe fittings include couplers, tees, adaptors, bushings, plugs, caps and crosses.

Tees are used to create right-angle connections between PVC pipes and it also allows three separate pipes to be joined in one location. The outside diameter of all the pipes must be the same as the inner diameter of the tee pipe fitting.  Similarly, couplers are used to join just two PVC pipe fittings together.

There are two main types of adaptors – male and female. These are designed to help join a piece of threaded pipe to a piece of slip pipe. An adaptor with a threaded interior is female whereas a threaded exterior indicates that it is a male PVC adaptor.

Bushings are most commonly used to extend a non-threaded pipe section with a pipe with a threaded end. They come in a variety of different sizes.

A PVC plug fitting is used to stop the flow of water in any direction by inserting and securing it into the end of a pipe whereas a cap is fitted over the end of the pipe.

Finally, crosses are used when you need to join four pipes together at one intersection. They form the shape of a cross.

Advantages and Disadvantages of PVC Pipe Fittings

PVC pipe fittings are a lot quieter than other types of pipes when used to transport high pressure water or air. It is also self-insulating meaning it can withstand high water temperatures.

They have a very long lifespan and are highly resistant to corrosion and chemicals. The smooth internal surface of PVC pipe fittings means they offer fantastic flow properties and there is no attachment of internal sediments to the pipes.

There are disadvantages however. The main disadvantage of PVC pipe fittings is that they are less flame resistant than other popular materials such as copper.

PVC pipe fittings are also quite bulky and are not as suitable for fitting into small places as copper is. Some people have also claimed that using PVC pipe fittings to transport their water has meant that they have a slight plastic-y taste to their water.

Where Can You Find Them?

They are used for a variety of purposes; however they are most commonly used in residential and industrial situations for carrying materials such as water, slurries, chemicals, flammable gases and for fire sprinkler systems.

When used for plumbing, brass pipe fittings are best suited to hot-water distribution lines as they last longer than other types of metals such as steel. They can be used for cold-water distribution however they don’t work as well under cold conditions as other materials.

Types and Sizes

Brass pipe fittings come in a huge range of types and sizes. There are eight most commonly used brass pipe fittings: pipe adaptors, pipe couplings, pipe elbows, pipe nipples, pipe unions, pipe tees, pipe plugs and pipe wyes. All the different fittings serve different purposes, for example the brass pipe coupling are used to either extend or terminate a pipe run. They can also be used to change the pipe size (known as reduced couplings).

The types of brass pipe fittings are not limited to those eight, however, and there are brass pipe fittings manufactured to suit practically every conceivable requirement and usage.

They come in a range of shapes and thread sizes allowing you to connect, control and adapt the flow of air or liquid within the pipe.

Sizes vary depending on their purpose. Residential brass pipe fittings are considerably smaller than those used in industrial applications. Brass pipe fittings commonly come in sizes ranging from 1/8 to 12 inches in diameter. However, they can be found in sizes up to 36 inches in diameter if required.

Brass pipe fittings can also come in various types of finishes. This is largely for decorative purposes, particularly when the fittings are exposed. Some of the finishes include: antique brass, nickel finish, polished brass, lacquered brass and chrome plated brass pipe fittings.

Brass pipe fittings are best known for their incredible strength along with excellent ductility in high temperatures. However, a disadvantage is that they are not quite as ductile in colder temperatures. They have good conductivity and a low magnetic permeability.

Brass pipe fittings are slightly more expensive than similar different materials such as galvanized steel and wrought-iron; however they do offer a range of added benefits. Brass pipe fittings do not rust, meaning that you can use a small size of brass pipe and fitting than steel without losing any water volume.

Brass pipe fittings are much easier to thread and bend than steel and iron.

There are also several disadvantages however. The main disadvantage of brass pipe fittings is that they are very heavy. This makes them expensive to ship and harder to maneuver. 

Brass pipe fittings should not be used with iron pipes or vice versa, as when the two dissimilar metals are in contact they can cause electrolytic decomposition of the iron.
