What is a PVC spigot plug?

What is a PVC spigot plug?

The end connection of a fitting that is to be assembled into another fitting is called the “Spigot.” The spigot end of a fitting has the same outside diameter as pipe. The common female connection of PVC fittings is referred to as the socket or hub, and the spigot end of a fitting can be inserted into a Hub or Socket.

What is PVC hub?

Hub – a type of DWV fitting end that allows pipe to slide into the end. MPT – aka MIPT, Male (Iron) Pipe Thread – a type of threaded end found on PVC or CPVC fittings where the outside of the fitting is threaded to facilitate connection with a female pipe threaded end (FPT).

What is PVC union?

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. This means that wherever you use a PVC union to connect pipes together these pipes can be disconnected and worked on with relative ease.

What does a PVC coupling do?

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 couplings used for?

How tight should a PVC Union be?

The right way to assemble a threaded PVC joint-Schedule 40 or 80 is finger tight plus one to two turns-no more. Two turns past finger tight plus the stress of the system pressure is within the tensile strength of one-inch PVC. ([1,788 psi x 2] + 2,000 psi = 5,576 psi). Don’t use Teflon tape, Teflon paste or pipe dope.

Does PVC have to be fully seated?

PVC pipe is designed to seat neatly into fittings and other pipes to create a tight seal. Water and gas are commonly pumped through PVC pipe, so a properly seated joint is essential.

What can I use instead of PVC primer?

The only substitute for primer is cleaner. Both contain MEK (Methyl Ethyl Keytone) and Acytone (and other mean chemicals). The main difference between the two is that primer contains purple dye. That way you can check your work and it also offers a security blanket.

Can a PVC fitting be a socket or spigot?

A socket/spigot fitting can work as either a socket or spigot. For example, a ½” socket connection can slip over ½” PVC pipe or inside a larger ¾” PVC fitting. This is where the most confusion is seen, as it’s not always understood that a fitting can be connected directly to another fitting rather than to the pipe.

What are the different types of PVC fittings?

Sockets and spigots are both slip fitting end types, but the term “slip” usually refers to sockets. A socket is a fitting that simply goes over the end of a pipe. A 1″ socket end will fit on a 1″ pipe. These are extremely common. Many PVC couplings have socketed ends. A commonly used abbreviation for “socket” is “soc.”

What’s the difference between a SOC and a socket?

A commonly used abbreviation for “socket” is “soc.” A spigot fits inside a socket, so it is the same size around as regular pipe. When you need to attach a fitting to another fitting, you use a spigot end. In their function, sockets are the female and spigots are the male.

Can a slip fitting be used with PVC pipe?

Note, socket/spigot slip fittings are compatible across a wide variety of fittings, not just white PVC fittings. One way to help keep them straight is to remember the spigot end of a fitting has the same outside diameter as pipe. PVC pipe itself never works as a female connection.
