What type of hose appliance features one female inlet and two or more male outlets?

The correct answer is a Siamese. A Siamese hose appliance is designed specifically to combine the flows from two or more lines into a single discharge line. This configuration typically features one female inlet that connects to the supply of water and has two or more male outlets where hoses can be attached to distribute the water to different directions or points of use.

In contrast, a yoke is generally not recognized as a hose appliance; it may refer to support structures or devices. A Wye typically has one inlet and two outlets, allowing for equal distribution of water from a single source to multiple hoses. A splitter, while it sounds similar and often is used interchangeably in casual conversation, typically refers to appliances that split a single hose line into two without creating a combined flow, as is the case with a Siamese. Understanding the distinct functions and configurations of these appliances helps clarify their unique roles in firefighting operations.
