What materials are most commonly used to make pneumatic hoses?

Reinforced rubber or polyurethane is the most common choice for making pneumatic hoses due to their ability to withstand high pressure and offer flexibility and durability. These materials are specially designed to handle the rigorous conditions found in pneumatic systems, including exposure to various temperatures and potential abrasions from the working environment.

Reinforced rubber provides excellent resilience and can handle high burst pressures, making it ideal for demanding applications. Similarly, polyurethane is known for its lightweight properties, toughness, and resistance to kinking and abrasion, which are critical for maintaining consistent airflow and performance in pneumatic systems.

In contrast, the other materials listed do not offer the same suitability for this specific application. Metal and steel, for example, are typically not used for hoses due to their rigidity and susceptibility to corrosion, which could lead to failure in a pneumatic application. Plastic and vinyl may not have the same durability or flexibility required for high-pressure environments as reinforced rubber or polyurethane. Finally, linen and cotton are not appropriate materials for pneumatic hoses because they lack the strength and resistance to wear that is necessary for such applications.
