The use of metallic gasket material for a flange union in gasoline conduction is appropriate due to its durability and resistance to the chemical properties of gasoline. Metallic gaskets are generally designed to withstand high pressures and temperatures, making them ideal for applications involving flammable and volatile substances such as gasoline.

Metallic materials typically provide better sealing capabilities and can handle the thermal expansion or contraction that occurs in gas lines, ensuring a tighter and more secure seal over time. Moreover, they are less susceptible to degradation compared with organic materials when exposed to fuels, oils, and various chemicals, thus enhancing the safety and longevity of the union.

In contrast, rubber, while flexible and often effective in lower temperature and pressure environments, may not provide the necessary resilience against gasoline and can deteriorate over time. Fiberglass might not be appropriate in this application due to its brittleness and inability to provide a reliable seal under varying pressures. Paper gaskets are also unsuitable, as they are generally used in low-pressure applications and lack the chemical resistance needed when in contact with gasoline.
