What is the maximum length for non-metal flexible connectors used in dental gas and vacuum systems?

The maximum length for non-metal flexible connectors used in dental gas and vacuum systems is established based on safety regulations outlined in NFPA 99. The code specifies that non-metal flexible connectors should not exceed 5 feet in length. This limitation is important as it helps to ensure that the integrity of the system is maintained, minimizing the risk of leaks and maintaining the pressure required for effective functioning of the gas and vacuum systems.

Using longer connectors could lead to potential complications, such as increased backpressure or airflow resistance, which can compromise the performance of dental gas systems. By adhering to the established maximum length, practitioners can ensure the safety and reliability of their systems while complying with the standards set by NFPA 99.
