We offer a variety of materials for sealing gaskets, including rubber (such as nitrile rubber, silicone rubber, fluorine rubber, etc.), metal (such as stainless steel, carbon steel, etc.), asbestos, graphite, and more. Different materials have different characteristics and are suitable for different working conditions and media.



The specific temperature and pressure range depends on the selected gasket material and design. Generally, our sealing gaskets can work in a temperature range of -50°C to 200°C, and the pressure range can vary from low pressure to high pressure. The specific parameters will be clearly indicated in the product manual.

When choosing a sealing gasket, several factors need to be considered, such as the working medium, temperature, pressure, seal surface form, etc. Our professional team can provide advice and selection guidance based on your specific needs to ensure that you choose the most suitable sealing gasket.
