What is a key consideration when selecting fittings for high-pressure applications?

In high-pressure applications, the pressure rating of the fittings is crucial because it indicates the maximum pressure the fittings can withstand safely without failing. This ensures that the system operates reliably under the expected conditions. Fittings that do not meet the required pressure rating can lead to catastrophic failures, potentially causing leaks, ruptures, or hazardous situations.

While cost, chemical compatibility, and availability are also important factors in the selection process, they do not directly address the fundamental need for safety and reliability in high-pressure environments. Therefore, understanding and selecting fittings based on their appropriate pressure rating is essential to maintaining the integrity and safety of the entire system.
