A union is similar to a coupling, except it is designed to allow quick and convenient disconnection of pipes for maintenance or fixture replacement. While a coupling would require either solvent welding,soldering or being able to rotate with all the pipes adjacent as with a threaded coupling.
A union provides a simple transition, allowing easy connection or disconnection at any future time.

What is the difference between a half coupling and a full coupling?
half coupling used to take branch from header ie: 2" header to 3/4' branch. where full coupling used to connect to straight pipe. ie: 2" to 2" pipe connection.

What is the difference between flange and coupling?
flange is a protruding rim, edge, collar, as on a wheel or a pipe, shaft, used to strengthen an object, hold it place, or attach to another object.while coupling is a device to connect two shaft together at their ends for the purpose of transmitting power.
How do you untighten a pipe union?
A pipe union is a three piece fitting with a big nut in the center. Loosen the big nut and the joined pipes will separate. Are you sure you don't mean a coupling? A coupling is a one piece tube with female threads all the way through it. These are trickier to untighten because by loosening one side of the fitting, you'll be tightening the other side, which will usually bottom out the fitting on the side that's being tightened before the side that's being loosened comes out of the fitting. In short, the way to untighten a coupling is by either cutting the pipe, spinning the coupling and replacing things as needed OR by spinning the entire run of pipe...

Difference between coupling and pipe union?
A coupling is a threaded or soldered solid fitting, a union is a fitting that joins two pipes and can be taken apart with wrenches.

What is the difference between a socket and a coupling?
A socket is a female fitting that connects to a pipe or tubing, while a coupling is a device that connects two pipes or tubes together. Couplings can be either rigid or flexible, while sockets are typically fixed and do not allow movement.
What is the difference between a threaded black iron pipe coupling and a threaded black sleeve?
A coupling has internal threads and a sleeve is used to protect piping from coming in contact with cement of from being crushed by structual weight. A sleeve is used when pipe is passing through walls and foundations and through floors
Do you use teflon tape with a union coupling?
You use it on the pipe that the union is connected to, but not on the threads of the union itself. The union seals where the two halves join and there is no liquid or gas in contact with the threaded part of the union.

How can I effectively repair a galvanized pipe using a repair coupling?
To effectively repair a galvanized pipe using a repair coupling, follow these steps: Turn off the water supply to the pipe. Cut out the damaged section of the pipe using a pipe cutter. Clean the cut ends of the pipe with a wire brush. Slide the repair coupling onto one end of the pipe. Slide the other end of the pipe into the other side of the repair coupling. Tighten the screws on the repair coupling to secure it in place. Turn the water supply back on and check for leaks.
