What type of connectors must all tubing connectors utilize?

The requirement for all tubing connectors to utilize Type 304 stainless steel industrial type connectors is based on the need for durability, corrosion resistance, and compatibility with compressed natural gas (CNG) applications. Type 304 stainless steel is known for its excellent resistance to oxidation and corrosion, which is crucial when handling CNG, as it can react adversely with certain materials over time.

Using Type 304 stainless steel also ensures that the connectors can withstand the high pressures commonly associated with CNG systems. Its strength and stability under pressure make it a reliable choice for maintaining the integrity of tubing systems designed to transport gas safely and effectively.

Other materials, such as standard plastic connectors or aluminum adjustable connectors, may not provide the necessary structural integrity and resistance needed in high-pressure gas systems and could lead to potential failures or leaks. Similarly, while bronze connectors have certain advantages in other applications, they do not match the performance characteristics of Type 304 stainless steel when it comes to CNG. Thus, Type 304 stainless steel industrial type connectors are the standard and recommended choice for ensuring safety and reliability in CNG systems.
