What is the primary purpose of a demand check fitting in a medical gas system?

The primary purpose of a demand check fitting in a medical gas system is to facilitate servicing. This component is often incorporated into systems where medical gas supply is required, as it allows for the disconnection of equipment from the gas supply without the risk of backflow. When servicing or maintenance of the medical gas supply system is necessary, the demand check fitting enables technicians to safely isolate sections of the system, ensuring that gas flow can be managed effectively while minimizing the risk of contamination or gas leakage.

In systems where medical gases are involved, maintaining safety and functionality is crucial. The demand check fitting plays a significant role in ensuring that when adjustments or repairs are needed, the risks posed to both personnel and patients are mitigated.
