Pipe fittings are the one responsible in the correlation of pipelines, whether copper, plastic ABS, CPVC, or steel. It permits the water lines to run in places where it is needed: under a house, over your ceiling or around a corner. As an example, imagine that you have to lay a pipeline around a corner. You have to place a pipe with the side's length and an elbow at its end. That elbow is one sample of plumbing pipe fitting. It is a pipe with a short length, which we may call as connector since it is the one that connect the both ends of pipe, having a 90-degree bend. It provides a clean turn through its secured connection at both ends.
There are two ways of connecting pipe fittings into pipes- it can be by slip fit or by threads. From the name itself, slip fit pipe uses sleeves which can slip into one another while threaded pipe screws together to connect. Those plastic pipes can be threaded or slip fit but those metal pipes can only be connected through threaded way. Pipe fittings are structured by male and female connectors: male slip fit, female slip fit, male threaded, and female threaded. Male slip fit has no thread and made to slip into a quite larger female sleeve which makes the female sleeve to be the receiver of a thinner male slip fit. Male threaded has an exterior threading and is build to screw within a pipe with larger diameter and internal threading. This leaves female threaded to function as a receiver of male threaded pipe fittings.
