Straight pipe fittings are linear pipes with male and galvanized iron. If you're not familiar with any of these materials, here's a quick summary.
* '''Galvanized Steel:''' Although this material was used once used to supply water, it was slowly phased out because of its ability to quickly corrode.
* '''Copper:''' This lightweight, durable metal can work with cold and hot water. Copper is resistant to corrosion, but it's also difficult to shape. Cuts must be done with precision and it must also be soldered.
* '''Chlorinated Polyvinyl Chloride (CPVC):''' If you're looking for an alternative to copper pipes, CPVCs are your best choice. These pipes have a yellowish color and cannot be buried underground. They can be used to transfer hot and cold water.
* '''Cross Linked Polyethylene (PEX):''' Transport hot and cold water throughout a house or apartment building with PEX piping.
* '''Cast Iron:''' Despite its weight, cast iron pipes are incredibly strong and have been used for drainage.
