AIR, 300 0 400°F Resistant O-Rings and Seals

AIR between 300°F and 400°F is also known as very hot air. It is commonly used in industrial processes such as metalworking, annealing, and heat treating. Very hot air is also used in some HVAC systems, as it can provide a comfortable environment for humans and other living creatures.

When rubber is exposed to very hot air, it can become susceptible to cracking, discoloration, and hardening. High temperatures can cause the rubber to become brittle and crack, leading to premature failure. Additionally, very hot air can cause rubber to become brittle and discolored over time, leading to further degradation and reduced performance. Heat can also cause rubber to swell and become soft, leading to potential leakage and decreased effectiveness.
