What pressure design minimum is required for the fittings of the CNG service hose?

The minimum pressure design requirement for the fittings of a CNG service hose is at least 5000 psig. This standard is critical because CNG systems operate at high pressures, and the components, including hose fittings, must be able to withstand these pressures safely. Ensuring that the fittings are rated for at least 5000 psig helps to prevent failures that could lead to leaks or catastrophic incidents due to the high-pressure nature of compressed natural gas.

Using fittings that meet or exceed this pressure requirement is essential for maintaining the integrity of the system, promoting safety for both operators and the public, and adhering to regulatory standards in installations and maintenance. Components rated lower than 5000 psig may not provide adequate safety margins, increasing the risk of equipment failure under operational conditions.
