Silicone and rubber gaskets offer numerous advantages, including resistance to temperature extremes, chemicals, and environmental factors. Their flexibility and resilience allow for effective sealing in dynamic and challenging conditions. Additionally, these gaskets provide vibration dampening, noise reduction, and electrical insulation, making them valuable components in a wide range of industrial and commercial applications.
