What should be done to ensure airtight connections when assembling the hose?

Using a rubber mallet to ensure connections are airtight is an effective method in securing hose assemblies. When properly utilized, a rubber mallet helps to gently seat the connections more firmly, minimizing any gaps that could lead to leaks. This method is particularly valuable in fire rescue operations where maintaining high-pressure integrity in hoses is crucial for safety and effectiveness in emergency water delivery.

In the context of hose assembly, achieving an airtight connection is critical. Tightening connections without additional steps may not guarantee a perfect seal, as it could leave room for air or water leaks. Similarly, the use of duct tape or glue is not suitable for hose connections. Duct tape can degrade over time and may not hold under pressure, while glue can make it difficult to disassemble hoses for maintenance or repairs, compromising the flexibility and functionality of the equipment. Thus, the approach of using a rubber mallet aligns best with the practical requirements of fire rescue operations.
