What sizes are hard suction hoses typically found in?

Hard suction hoses are generally used in fire service and other emergency management applications to draft water from static sources, such as ponds or tanks. The most common sizes for these hoses are typically within the range of 4 to 6 inches in diameter. This size allows for efficient water flow while still being manageable in terms of weight and flexibility during operations. It strikes a balance between providing a large volume of water and being practical for firefighters to handle and transport.

While larger sizes may be available, they are less commonly used for standard hard suction applications, as the increase in diameter can make the hoses more cumbersome and difficult to manage. Smaller sizes, such as those under 4 inches, are generally not suitable because they do not facilitate the necessary water volume in emergency situations. Therefore, the 4 to 6 inch range accurately reflects the typical configurations for hard suction hoses.
