Rubber O-rings are known for their outstanding sealing performance and long service life. In dynamic pressure applications, their durability can exceed that of conventional rubber seals by 5 to 10 times, and in certain conditions, they can even match the lifespan of the sealing substrate itself. This brings us to the question: how much temperature can a rubber O-ring withstand? Below, Kinton Seal has provided a detailed overview of temperature resistance ranges for different rubber materials.
General Temperature Resistance Range for Rubber Materials
The typical temperature tolerance for rubber materials is approximately 120°C. However, due to variations in material composition, high-temperature resistance can differ significantly. Let’s explore the temperature limits of some commonly used materials:
Nitrile Rubber (NBR): Capable of withstanding temperatures up to 130°C, with an operational range of -40°C to 120°C. We supply high quality seal kit like E312 boom cylinder seal kit.
Fluorine Rubber (FPM): Offers excellent high-temperature resistance, enduring up to 280°C. It also provides superior aging and oxidation resistance, with low gas permeability. Its working temperature range is -20°C to 280°C.
Ethylene Propylene Diene Monomer (EPDM): Operates within a temperature range of -50°C to 150°C, featuring resistance to hot water, steam, aging, and chemicals.
Silicone Rubber (SI): Suitable for temperatures ranging from -60°C to 180°C. Silicone is non-toxic, odorless, and often used in food packaging seals due to its safety profile.
