What type of coupling is used on the inside of a straight hose roll?

In a straight hose roll, the type of coupling used on the inside is a male coupling. This is because when hose is rolled straight, the male coupling allows for an easier connection to the pump or other hose sections. The design facilitates effective water flow and ensures that the connection is secure and leak-proof when coupled with a female coupling on another hose or fittings.

Male couplings are typically found at the end of the hose where it connects to other equipment, while female couplings are located on the opposing side to allow for connection to the male end of another line or apparatus. The specific design of the male coupling aids in reducing potential for kinked hoses and allows for seamless operation in the field.
