What alternative solution is used when the female threaded swivel is missing for connecting to the FDC?

When dealing with a situation where a female threaded swivel is absent for connecting to the Fire Department Connection (FDC), a speed swivel serves as the alternative solution. A speed swivel is specifically designed to facilitate quick and efficient connections and disconnections in fire service operations. This type of connection allows firefighters to adapt to various situations rapidly, ensuring that they can maintain their operations without unnecessary delays.

The speed swivel connects hoses with different types of threading or enables a connection to systems that wouldn't typically match. Its design focuses on speed and versatility, making it particularly advantageous in emergency scenarios where time is of the essence. Therefore, opting for a speed swivel in the absence of a female threaded swivel meets the need for a reliable and expedient connection to the FDC, allowing firefighters to manage their tasks effectively.

Other options, while they may have their uses in firefighting and equipment management, do not provide the specific connection capabilities that a speed swivel offers, making it the most practical choice in this scenario.
