What type of hose is used to connect a fire department pumper directly to the large steamer outlet on a hydrant?

The type of hose that connects a fire department pumper directly to the large steamer outlet on a hydrant is a soft sleeve hose. This hose is specifically designed for these purposes because it is flexible and can easily accommodate the connection between the hydrant and the pumper.

Soft sleeve hoses are also built to handle the necessary pressure requirements when drawing water from hydrants, ensuring that the pumper receives a sufficient flow of water. They are typically constructed in a way that allows them to fold and move easily, which is essential when navigating the terrain around a fire scene.

While supply hoses and large diameter hoses are also used for similar connections in some scenarios, soft sleeve hoses are generally the industry standard specifically for hooking up hydrants due to their lightweight and maneuverable characteristics. Attack hoses, on the other hand, are designed primarily for delivering water to the fire scene rather than connecting to hydrants.
