Which type of hose coupling is commonly used in firefighting?

The commonly used type of hose coupling in firefighting is the threaded coupling. This design features male and female threads that allow hoses to be securely fastened together, ensuring a tight seal that can withstand the high pressures often encountered during firefighting operations. The threaded coupling is beneficial because it can be easily connected and disconnected, making it practical for firefighters who may need to quickly assemble or disassemble their equipment in the heat of a situation.

Moreover, threaded couplings are quite durable and can resist the wear and tear associated with firefighting environments, such as exposure to heat, water, and abrasives. Their reliability is crucial when dealing with water supply lines, as a secure connection prevents leaks that could jeopardize firefighting efforts.

While cam lock couplings are used in various industrial applications and can offer easy, quick connection options, they are not as prevalent in firefighting as threaded couplings. Similarly, knock-on and screw-on couplings, while they may serve specific purposes in some fields, do not provide the same level of safety and security necessary for firefighting scenarios. There's a strong emphasis in the firefighting community on using couplings that ensure secure connections capable of handling the rigorous demands of the job, which makes the threaded coupling the preferred choice
