Plumbing Fittings

Plumbing fittings are the materials that hold the entire plumbing system to specific pressures and to exact areas. The fittings general refer to the wide variety of items that branch, reduce, or maximize the flow of the liquid within them. There are several common fittings that we will discuss here from the elbow, tee, cross and cap, to the plug, nipple and barb. The first major feature of the fitting is that it allows the plumber to manipulate straight tubing to move along and around obstacles, such as important or load bearing pillars in the building. The advantage of this is that you can move the desired liquid throughout the building with a one-time adaptation to the piping. The elbow, tee, and cross are all means of moving water around and distributing it to various areas. The cross is used in sprinkler systems as it has on inlet and three outlets. If a pipe diameter reduction is placed on any of the pieces it is predicated with the term: reducer X. For example a reducer elbow has the inlet with a greater diameter and the outlet with a smaller diameter.

The second most prominent usage, although still widely popular, is the reduction of the water flow. By reducing the interior diameter of the piping you can increase the pressure at a given point. Valves technically fall under this category as they regulate water flow and so fall under the broad category of plumbing fittings. Generally, they are given their own category as they’re vitally important to the development of properly pressurized aqua-regulatory systems. The plug and cap represent different methods of ending a pipe, but due to their placement have male and female fittings respectively. The male/female fittings are described further in the FAQ section. A barb is used to connect flexible hoses to straight pipe and has a series of hard ridges to hold securely to the hose.
