PVC unions and PVC pipe union connectors are pipe fittings designed to connect two pipes together without the use of a sealant or traditional glued coupling. The advantage of using PVC pipe unions is that the pipes that are connected using PVC pipe unions can be taken apart and put back together again without the use of specialized tools.

What is a union fitting?
A union is a threaded fitting which allows the pipe work to be separated and reconnected without any horizontal movement in the pipe. It can be a standalone pipe fitting connecting two pieces of pipe, or an integral part of another fitting (such as a ball valve) which allows it to be separated.

What is the difference between a coupling and a union?
The basic difference between a coupling and a union is that a coupling is for joining pipe to pipe or pipe to a swedge. A union is made for joining and disassemble of a part of a piping system (a steam trap or control valve, etc) for maintenance or replacement.
When would you use a union fitting?
A pipe union is a type of fitting that is used to connect two pipes together while providing an easy way to disconnect the pipes in case that is necessary.
What is the purpose of a plumbing union?
Pipe unions and couplings are both types of fittings that allow you to repair breaks in plumbing lines, but there's an important difference between them: A coupling makes a permanent connection, while a union makes one that can be separated and reassembled repeatedly.
How do you stop a PVC union from leaking?
Fiberglass Resin Tape or Cloth If you're looking for a temporary repair for a leaking PVC pipe, fiberglass resin tape can slow the damage. The fiberglass tape makes repair simple by using a water-activated resin that hardens around the pipe and slows the leaking.
Which way does a PVC union go?
As for the orientation of the union, I always make sure that the nut is at the top so that when it is taken apart it doesn't fall down the pipe. Plus not having to lift the nut into place while lining up the fitting and making sure the o-ring is in place makes things a bit easier.

What is a flange union?
[′flanj ‚yün·yən] (engineering) A pair of flanges that are screwed to the ends of pipes and then bolted or welded together to hold two pipes together.
What is the difference between union and socket?
There are two connection forms for unions, i.e. socket welding and threaded connection. The socket welding is to insert the steel pipe into the socket to get welded. Therefore, it is called “plug-in union”. The threaded connection is to screw the steel pipe into the screw hole for connection.
What is a half union fitting?
Product Description This Anderson Metals half union compression tube fitting is made of brass, has a flared tube connection and a male NPT connection, and is suitable for use with fuel and gas systems. It is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability.
What is a pipe union?
A pipe union is a type of fitting that is used to connect two pipes together while providing an easy way to disconnect the pipes in case that is necessary. The union will create a seal between two pipes so that one does not need to use the conventional glued coupling method, of a PVC fitting and glue to connect two pipe lengths together.
Is PVC union cheaper than metal?
PVC unions are inexpensive alternatives to metal and other unions. They have lower pressure and heat ratings, but in most cases PVC unions will be more than capable for the job you are doing. PVC unions are also eco-friendly, and are more malleable and easier to use than the alternative.
What size fitting should I use for PVC?
The most important thing when working with PVC pipe and fittings is the nominal size. A 1" fi tting will fit on a 1" pipe, regardless of whether either one is schedule 40 or 80. So, while a 1" socket fitting has an opening wider than 1" across, it will fit on a 1" pipe because the OD of that pipe is also greater than 1".
What is a coupling in PVC?
Couplings are one of the most simple (and inexpensive) types of PVC fittings. They are a small part that connects or "couples" one part to another, usually permanently. They can connect pipe to pipe and pipe to fitting. Some of them even reduce so you can connect a small pipe to a large pipe or vice versa.
What are PVC elbows?
Elbows are most commonly available in 90-degree angles and 45-degree angles, so your pipeline can be directed however you want it. Side elbows are a slightly different piece that are commonly used as corners in projects such as canopies, tents, displays, and boxes. They have three ends instead of two. Most elbows have slip socket ends, but threaded versions are available.
Why does PVC have slip ends?
"Slip" in PVC does not mean the connection will be slippery, but rather that the fitting will slip right over the pipe. When putting pipe into a slip fitting, the connection may seem tight, but to transport any liquid media, it will need to be sealed.
What is the OD of a PVC pipe?
Well here's the confusing part: the outer diameter (OD) of PVC pipe is greater than the size in its name. That means that 1" PVC pipe will have an OD that is greater than 1", and a 1" PVC fitting will have an even larger OD than the pipe. The most important thing when working with PVC pipe and fittings is the nominal size.
Why do people use threaded fittings?
Threaded fittings need to be sealed differently. The main reason people use threaded parts is so that they can be taken apart if necessary. PVC cement bonds pipe together, so if it is used on threaded joints, it will make a seal, but the threads will become useless.
What is the difference between furniture grade fittings and regular fittings?
Often our customers ask us, "What is the difference between furniture grade fittings and regular fittings?" The answer is pretty simple: our furniture grade fittings have no manufacturer printing or bar codes. They are clean white or black with nothing printed on them. This makes them great for applications where the pipe will be visible, whether or not it is actually for furniture. The sizes are the same as regular fitting sizes. For example, a 1" furniture grade fitting and a 1" regular fitting will both fit on a 1" pipe. Also, they are just as durable as the rest of our PVC fittings.
Why is PVC union used?
This allows an uninterrupted flow when they are used in systems containing fluid, making them a good choice when a system requires a steady rate of flow. PVC resists corrosion, so these unions can be used in locations where metal fittings are not ideal, such as underwater or underground.
What is the diameter of a Schedule 40 union?
Schedule 40 PVC unions are available in diameters from 1/2 inch to 2 inches.
What is Schedule 40 PVC used for?
Since Schedule 40 PVC is commonly used in building temporary structures, like tent supports, these unions are a popular way to join pipes. They can be quickly taken apart when the structure is no longer needed.
Can a Schedule 40 PVC pipe be removed?
Unlike couplings, however, unions are designed to be a semi-permanent solution. These can easily be removed and replaced as needed, because they require no adhesive. This makes them the best choice when contractors are creating systems that may need to be changed or updated at a later date, or when creating systems that need to be regularly taken apart, either to move them or to inspect them.
What is PVC pipe connector?
PVC connectors, commonly known as fittings, bring everything together. As the name suggests, they connect the pipes together. While there are several types of PVC pipe connectors, all of them can be sorted into two categories: Plumbing grade connectors. Furniture grade connectors.
How many PVC pipes can you connect?
With them, you can connect four PVC pipes. They are more limited compared to tees, and they come in less materials. Because of this, many professionals opt to use several tees instead of a cross connector. Other than PVC, crosses come in malleable and brass.
What are the different types of connectors?
While some look like you’d imagine fittings to look like, others can seem intimidating. Some of the common connector types are: 1 Adapters 2 Bushings 3 Caps and plugs 4 Couplings 5 Elbows 6 Flanges 7 Nipples 8 Tees 9 Crosses 10 Saddle Tees 11 Unions 12 Wyes
How to add a new pipe without cutting PVC?
You can also find them under the name ‘snap-tee.’ They are a great way to add a new pipeline without cutting an existing PVC pipe. Commonly, people use saddle tees on irrigation systems. This way, you will easily add another sprinkler line. To complete this task, you need to take a saddle tee and glue it to the pipe. After everything is set, you have to drill another hole, and everything is good to go.
What is a cap on a pipe?
Caps, as their name suggests, cap the end of the pipe. You put them above the pipe to close it. They can be glued, threaded, or soldered on the pipe.
What is plumbing grade connector?
