What type of elbow has a female connection on one side and a male connection on the other?

A street elbow is specifically designed with a female connection on one side and a male connection on the other. This configuration allows it to be used in situations where you need to change the direction of piping while also adapting to different fitting types. The male end typically connects directly to a pipe or fitting, while the female end allows for the connection to another pipe or fitting.

In practical applications, this type of elbow is useful for creating a more compact installation because it combines an angle change with a direct male-to-female fitting without requiring additional adapters. This design helps reduce the overall length of the piping system while maintaining a secure connection.

Other elbow types, such as the long elbow or short elbow, primarily define the radius of the bend but do not specifically indicate male or female connection types. A reducing elbow is used to connect two pipes of different diameters and does not fit the male-female connection criteria as described in the question.
