What is the difference between coupling and fittings?
Union Fittings – Unions are similar to couplings in that they connect two similar pipes. With pipe unions, a nut or threaded ring in the middle of the fitting is tightened to join two pipes. It can be easily removed by loosening the ring to disconnect the pipes, while a coupling must to be cut out to disconnect.
What is the difference between coupling and adapter?
A coupler is a very short pipe or tube that has a socket at one (or both) ends. This allows two pipes or tubes to be joined (or coupled), welded or soldered together. An adapter is used to convert the attributes of one device to another.

What is the difference between rigid coupling and flexible coupling?
Rigid couplings provide a rigid connection; the two shafts are firmly connected, and the coupling allows for a smooth transmission of torque throughout the system. Flexible couplings create flexible connections, and the components can lose some of the torque power through the interaction.
What is difference between union and coupling?
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.
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 the difference between cap and plug?
Often the two words are used interchangeably. Caps, however, push or thread over the outside of a part, while plugs push or thread inside the part. Caps and plugs prevent dirt, dust, moisture, liquids and any other contaminants from entering the opening during manufacturing, masking, storage and transportation.
What is full coupling in piping?
Full Coupling is used for connecting small bore pipes. It used to connect pipe to pipe or pipe to swage or nipple. It can be threaded or socket ends types. A socket weld full coupling is used to join small-bore plain end pipes where the pipe spec requirement is socket weld.
What is NPT coupling?
The coupling is a stainless steel 304 cast pipe fitting with female National Pipe Taper (NPT) threads for connecting and extending pipes going in the same direction. It has NPT threads for connecting to male pipes with a tighter seal than straight threads.
What are the two types of plumbing systems?
The Different Types of Plumbing. There are three different types of plumbing systems; sanitary drainage, stormwater drainage and potable water. Each of these systems have their own unique functions and purposes.
What is a pipe coupling?
Pipe Coupling is a very short length of pipe or tube. It has socket or female pipe threads at one or both ends. Pipe coupling allows two pipes or tubes of equal or different sizes to be joined together to make a long pipe run. The various functions that a Pipe Coupling or Coupler can serve are as follows: It helps to extend or terminate pipe runs.
What is the difference between a pipe coupling and a union?
The main difference between a coupling and a union is that coupling is normally used for permanent joining But a union is used for joining and disassemble a part of a piping system for fixing, maintenance or replacement. Few more related resources for you.
What is a socket weld?
It can be threaded or socket ends types. A socket weld full coupling is used to join small-bore plain end pipes where the pipe spec requirement is socket weld. A threaded full coupling is used to join small bore pipes with threaded ends.
What is a permanent pipe coupling?
Permanent pipe couplings create permanent piping joints using soldering or brazing in the case of steel or copper pipes or adhesives in the case of PVC pipes. When correctly installed, these permanent joints offer excellent rigidity and sealing characteristics. Permanent Pipe Couplings are used where no future changes in the piping are foreseen.
Why is slip coupling made without stop?
Slip coupling is deliberately made without any internal stop, to allow it to be slipped into place in tight locations, such as the repair of a pipe that has a small leak due to corrosion or freeze bursting, or which had to be cut temporarily for some reason.
What is compression coupling?
A compression coupling connects two perfectly aligned pipes in which a slotted tapered sleeve is placed over the junction and two flanges are drawn over the sleeve so that they automatically center the pipes and provide sufficient contact pressure.
Is a pipe coupling permanent?
They may be rigid or flexible depending on the amount of movement the pipe is subjected to and may also be permanent or removable. A pipe coupling can be increased or reduced in internal diameter to join different sized pipes (like T or cross-shaped) to join more than two pipes, or angled to form bends.
What is a pipe coupling?
A pipe coupling, sometimes also called a coupler, is a short length of tube or pipe used to connect pipes of varying types and sizes. In water and wastewater piping repair, couplings can be used to terminate or extend pipe runs, change the size of pipe, or repair breaks or leaks. Couplings offer a quick and reliable way to connect different pipe ...
What is a coupling in plumbing?
Couplings offer a quick and reliable way to connect different pipe sections without compromising continuity and integrity. Couplings can be used to repair various types of water and sewer line connections, providing both flexibility and resilience.
What is an electrofusion coupling?
Electrofusion couplings are used to connect HDPE pipes using electrofusion fittings with copper wires embedded in the fitting interior. An electrofusion processor is used to create an electric current which then runs through the copper wires, generating heat and melting the HDPE outside the pipe and inside the fitting.
Why are couplings important?
They are used to join two sections of pipe in a way that maintains their integrity and continuity. Along with different kinds of pipe repair clamps, couplings are an indispensable piece of equipment for piping repair.
Who makes hymax couplings?
Hymax couplings. They are produced by Krausz and are carefully designed to address every pipe joining need. Hymax couplings can join a wide array of pipe sizes and types, and are made from lightweight materials that enable easy installation and high durability.
Is a pipe coupling flexible?
Pipe couplings come in a variety of types and configurations. For instance, they can be flexible or rigid depending on the specific pipe movements. In the case of water and wastewater piping, the couplings should be malleable and suitable to numerous pipe sizes and types.
What is the difference between a half and full coupling?
The main difference of half coupling and full coupling is that the half coupling only has threads at one end and the full coupling has threads at both ends.
What is a threaded half coupling?
The threaded pipe half coupling is a short length of pipe used to connect two pieces of pipe without the need for much space. A two inch threaded half coupling can have either male threads at one end or female threads and no thread on the other end.
What Are The Different Types of PVC Couplings?
Full coupling is used for connecting small bore pipes. They find use to connect pipe to pipe or pipe to swage or nipple. Full couplings have both ends of threaded or socket welded connection. These couplings can be threaded or socket ends types.
Internal Couplings
These couplings connect inside PVC pipe and leave a smooth appearance.
Permanent Couplings
In the case of steel or copper tubing or adhesives, permanent pipe couplings generally make use of soldering or brazing in the case of PVC pipes. If properly mounted, these permanent couplings provide excellent rigidity, outstanding stability, and sealing properties where no potential piping improvements are foreseen.
Removable Couplings
Removable pipe couplings are most commonly of a threaded design that allows them to be screwed onto the pipes to be joined and tightened. The ends of the pipes are also threaded, and the coupling is conveniently sealed and set with hemp or sealing tape and screwed onto both pipes.
What is a full merchant coupling?
Full merchant couplings are available in black, galvanized and stainless steel materials. Full merchant couplings are used when a stronger coupling fitting is needed. For example, you can use a full merchant coupling in a drop pipe that’s in a water well because it would be holding the weight of the pipe, water and the submersible pump. If an even stronger coupling is required, there are drop pipe couplings available that are specific for these applications. Black full merchant couplings can also be used in applications where welding is required.
Why are tapered threads better than straight threads?
Second, tapered threads seal better. They seal better because the threads get tighter the further down the coupling, while straight threads stay the same width throughout.
Do merchant couplings need to be chamfered?
All merchant couplings are chamfered before they are threaded. This means that before the threading is done, a chamfer is created. It can be tricky to tell where the threads start on the chamfer, but it helps start threading the pipe into the coupling.
Can you use black merchant couplings in plumbing?
Black full merchant couplings can also be used in applications where welding is required. Please note that full merchant couplings should never be used as a pipe fitting in a plumbing system where a watertight seal is critical. However, taper-tapped merchant couplings would be acceptable to use for this type of application.
