In high-pressure CO2 piping, the required fitting class is which?

Fittings must be chosen to handle the maximum pressure the system may see. Each fitting carries a pressure class that defines the highest pressure it can safely carry at a given temperature. In high‑pressure CO2 piping, the system can reach substantial pressures, and the fittings used must have enough rating to prevent leaks or failure, even during pressure surges or temperature changes. Lower-rated classes are intended for much lighter services and would not provide adequate margin for CO2’s demanding conditions. Class 600 fittings are designed to withstand the higher end of common high‑pressure gas applications, offering the needed strength and margin for CO2 service without stepping up to unnecessarily heavier or more expensive options. That is why this rating is considered appropriate for high‑pressure CO2 piping.
