The Multi-tooth Fire Hose Coupling typically consists of an internal tooth ring, external tooth sleeve, and a seal ring. The precise meshing of the internal and external teeth achieves a rigid pipe connection, and the pressure transfer between the teeth enhances its vibration resistance, making it suitable for high-pressure firefighting systems.
When connecting to the hose, the hose is placed over the outer side of the upper and lower tailpipes, and is secured by clamps that compress and firmly fix the connection.
