Black fittings (black malleable iron fittings) are used to make connections to black iron pipe. Black iron pipe is used to transport natural and propane gas from the street or a tank to the home. Black iron pipe is also a popular choice in fire sprinkler systems due to its high heat resistance and for water supply lines due to its resistance to water damage. These fittings derive their name from the black oxide scale covering their surface.
There are many different types of black fittings, each serving a particular function.
45 & 90 Degree Elbows are used to change the direction of the flow of water 45 or 90 degrees. These fittings are connected directly to a black pipe.
45 & 90 Street Elbows are also used to change the direction of the flow of water 45 or 90 degrees. Unlike a standard elbow, a street elbow is connected to a black fitting.
Couplings are used to connect two pieces of black pipe together.
Caps are used to cover the outside end of a black pipe.
Black Plugs have male threaded ends for closing the end of a pipe. The plug inserts into female pipes or fittings that contain male NPT threads. These plugs have a square head which allows it to be installed easily with a wrench.
Tee Fittings are used to either combine or split fluid flow. They are also used to connect pipes of different diameters or for changing the direction of pipe runs.
Unions are similar to couplings and are used to connect two pieces of pipe together. A union is designed to allow quick and convenient disconnection of pipes for maintenance or fixture replacement.
