These are types of plumbing fittings made using brass. They are designed to help extend flow, change the direction of flow, combine, or divide flow in plumbing lines. Brass fittings are recommended in most applications such as food handling or chemical applications where no reactions are undesirable or intolerable. One of the common types of brass fittings you will get out there is the elbow. This is a type of fitting that helps to change the direction of liquid flow. Most elbow fittings are designed to change flow with 45 degrees to 90 degrees. Another common type of bras fitting is tees. These are used to help split flow. A tee is constructed with a single input and two outputs. Other types of fittings that are used to combine or split the flow include crosses and Wyes. If you want to extend the flow of a liquid, you need to connect several pipes. To do this effectively, you need to use couplings
and unions. Couplings are in most cases permanent; welded or fitted with nuts and bolts
. However, unions are designed to make removing easy. Other common types of brass fittings include flareless, hose barb, plugs ball valves, nipples and caps.
