A drip irrigation hose is used in the connection area of the branch pipe to the branch valve. The hose head holds the desired connection area (for example, connecting a branch pipe to a ball valve) firmly in place. It plays the role of an interface and is used in different places. The hose head is responsible for sealing.
It is better to know that in order to connect leaflet pipes or any type of main folding pipe to the equipment that has a female thread, a hose is used.
