What must all tubing connectors be made from?

Tubing connectors in compressed natural gas (CNG) systems must be made from Type 304 Stainless Steel due to its excellent corrosion resistance, durability, and ability to withstand high pressures. Type 304 is particularly suited for environments where exposure to moisture and chemicals is common, making it ideal for gas applications where integrity is essential.

The unique properties of Type 304 Stainless Steel, including its tensile strength and resistance to oxidation and scaling at elevated temperatures, contribute to the longevity and safety of CNG systems. Furthermore, using materials that can withstand the specific conditions of CNG storage and transport is crucial for preventing leaks and ensuring efficient operation.

Other materials mentioned do not meet these necessary criteria. For instance, Type 310 Stainless Steel may offer some benefits, but its specific high-temperature applications are not typically required for standard CNG tubing connectors. Plastic, while corrosion-resistant, generally lacks the tensile strength necessary to withstand the pressures found in CNG systems. Similarly, carbon steel may not provide adequate resistance to corrosion, especially in the presence of gas and moisture, making it unsuitable for long-term applications in CNG systems.
