What does it mean by coupling?
Loose coupling is an approach to interconnecting the components in a system or network so that those components, also called elements, depend on each other to the least extent practicable. Coupling refers to the degree of direct knowledge that one element has of another.
What does a pipe coupling look like?
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.
What is a PVC coupling used for?
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 is Shaft Coupling?
A shaft coupling is a mechanical component that connects the driveshaft and driven shaft of a motor, etc., in order to transmit power. Shaft couplings introduce mechanical flexibility, providing tolerance for shaft misalignment. The former is called a coupling and the latter is called a shaft coupling.

What is a coupling in plumbing?
Couplings are pipe fittings that help to extend or terminate pipe runs. These fittings are also used to change pipe size. It’s also used to repair a broken or leaking pipe. Most pipe installations require several lengths of pipe to be joined together or cut to facilitate changes in direction and crossing of obstacles.

What is permanent pipe coupling?
Permanent pipe couplings generally make use of soldering or brazing in the case of steel or copper pipes or adhesives in the case of PVC pipes. These permanent joints, if correctly installed, offer excellent rigidity and sealing characteristics where no future changes in the piping are foreseen.
What is a reduction coupling?
Reducing couplings are typically used where small process feeder lines are joined into large supply circuits or where small diameter fittings are installed. Reducing couplings will normally feature a simple, stepped down profile and screw onto the two lengths of pipe in the same way a standard pipe joint does.

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.

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.

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 (or coupler) (used in piping or plumbing) is a very short length of pipe or tube, with either socket or female threads at one or both ends that allow two pipes or tubes of equal or different sizes to be joined together. Couplings are pipe fittings that help to extend or terminate pipe runs.
Threaded Pipe Coupling Types
Full merchant coupling is used for connecting small bore pipes. It used to connect pipe to pipe or pipe to swage or nipple. It is threaded ends types. If the two ends of coupling are different (e.g. one BSP threaded and one NPT threaded), then it is usually referred to as an adapter.
Pipe Coupling Application
There is no limit to pipe fitting applications as long as there is no limit to valve applications. As the scope of piping uses continues to grow, its strength, versatility, very strong flow rates, and high chemical tolerance are ideally suitable qualities for the transport or conversion of liquids, steam, solids, and air from one stage to the next.
What is a plug in plumbing?
Plug is a component of plumbing component which is generally used to close pipe opening during inspections and repairs. Plug are generally contains male threads and are usually threaded to allow the plug to be removed for future use of the pipe.
What do you need to know about pipe fittings?
Pipes can be easy to shop for — all you need to know is the length and material. However, fittings are a completely different story. It’s crucial you use the correct fittings for the different areas. The material also plays an essential role since the wrong choice could lead to leaks or malfunctions within your system.
What is a cap in a pipe?
Cap. Cap is a type of pipe fitting which function is same as plug but the only difference is plug contain male threads and cap contain female threads which is screws on the male thread of pipe. These are available in different materials like rubber, copper, steel, plastic etc.
What is an adapter for a PVC pipe?
Adapter. When the pipes are not having special ends or plain ends then adaptors make them threaded either male or female whichever is needed with male having threads on the outside and the female on the inside. Adopters are generally used for copper and PVC pipes. Male adapters contain male threads and female adapters contains female threads.
What happens when a barb fitting is inserted?
As the barb fitting is inserted, the hose or tube will first expand and then relax. When the tube or hose relaxes and goes back to its original size, the connection is sealed and becomes difficult to undo. Barbed fittings are generally used in gas, air, and fluid control applications in low pressure.
What is a clean out fitting?
A clean-out fitting features removable parts that allow access to drains without the need to undo plumbing fixtures. Clean-outs will enable an auger (a type of drill) to enter and clean a clogged drain.
What are the parts of a union fitting?
So, this is also useful for maintaining purpose of pipe. Union fittings are made up of three parts: a nut, a female end, and a male end. They’re designed to connect two pipes with the possibility of being detached without damage or deformation to the pipes.
Flexible Couplings
Flexible couplings come in a wide variety of styles, sizes, and types. Typically, flexible couplings are not rated for underground use or where cast iron pipe is used and supported. Flexible couplings usually are a rubberized material and have band clamps on each end to form a watertight seal around the pipe.
No Hub Couplings
No hub couplings are meant specifically for joining lengths of pipes that do not have integral hubs. The most common use of no hub couplings is joining dissimilar material pipes underground in sewer and drain systems. Most no hub couplings carry ratings for underground use, unlike flexible couplings.
Which is Better? – No Hub or Flexible Couplings
In our opinion, a no hub coupling is superior for almost every application where you might use a flexible coupling. The design of no hub couplings offers several advantages over standard flexible couplings.
How Do You Install a No Hub Fitting?
Most flexible fittings don’t specify where, when and how the fitting to use the fittings. By and large, no hub fittings will list the specific testing and codes that the couplings meet. The manufacturers of no hub fittings usually give detailed instructions for installing the no hub fitting.
Flexible or No Hub Fittings – Making the Choice
In our opinion, any application that is suitable for flexible couplings deserves to use no hub couplings. No hub couplings typically have several advantages that make them more appropriate.
