Which of the following materials is NOT suitable for use as gasket material in a gas system?

Cork
Neoprene
Natural rubber
Fiberglass

The correct answer is: Fiberglass

Gaskets are critical components in gas systems, serving to create a seal between different parts to prevent leaks. For a gasket to be suitable, it must withstand the conditions present in a gas system, including temperature fluctuations, chemical exposure, and pressure changes. Fiberglass, while an excellent material for structural applications due to its strength and heat resistance, does not have the necessary pliability and sealing properties required in gas systems. It lacks the ability to compress and fill the small gaps that can occur between surfaces, which is essential for an effective gasket. As a result, fiberglass is typically not classified as a suitable material for gaskets in applications where sealing against gas is critical. In contrast, materials like cork, neoprene, and natural rubber possess better compressibility and resilience. These properties allow them to form a tight seal under varying conditions, making them appropriate for use in gasket applications within gas systems.
