The most common types are:
Slip: The slip fitting is the most common fitting. It is a female fitting that is meant to slip over the end of the pipe you are connecting it to, and is held there with some cement glue.
Fipt: Fipt is the term for the female threaded side of the PVC fitting. Female threaded PVC Fittings have threads on the outside of the fitting, and can be connected to any PVC item that has a Male (Mipt) end.
Mipt: Mipt is the term used for a male threaded side of a PVC fitting. Male threaded PVC items have threads on the inside of the object and can only be connected to another PVC item with a female (FIPT) side.
Spig: Spig is the term commonly used for Spigot ended fittings. These fittings are Male fittings, and are similar to slip fittings, but instead of sliding over the objects you are trying to connect, Spig fittings slide into the objects you are connecting. A spig fitting is the same as a piece of unthreaded PVC Pipe of the same size ( i.e. 1”, 2”…). You cannot connect a spig fitting to a PVC Pipe Length without first using another fitting because both are the same size.
Remember, for Spig and Slip fittings you always need to use glue otherwise the fittings won't hold. Other than that, you are now ready to go start your project. |
