A PTFE full face gasket is a sealing component designed to provide a reliable and leak-free seal in applications where a gasket is required to cover the entire face of a flange. PTFE full face gaskets find applications in various industries, including chemical processing, pharmaceutical, oil and gas, food and beverage, and many others. They are commonly used in flanged connections, such as pipeline systems, pumps, valves, and equipment requiring a secure and leak-free seal.
PTFE full face gaskets provide complete coverage of the flange face, ensuring a tight and reliable seal across the entire surface. This design is particularly beneficial in applications with irregular or damaged flange surfaces, where a full face gasket can help compensate for imperfections and provide a secure seal.
PTFE gaskets offer exceptional resistance to a wide range of chemicals, acids, solvents, and corrosive substances. They can withstand exposure to aggressive media without degradation, making them suitable for use in chemically harsh environments.
PTFE gaskets can handle high temperatures, ranging from cryogenic conditions up to approximately 260°C (500°F). They retain their sealing properties even at elevated temperatures, making them ideal for applications involving heat or thermal cycling.
PTFE has a non-stick surface, preventing the adhesion of substances and making the gasket easy to clean and maintain. This property is advantageous in applications where cleanliness and contamination prevention are critical.
PTFE full face gaskets are available in different sizes and thicknesses to match various flange dimensions and pressure ratings. They can be customized to meet specific application requirements and are typically used in conjunction with compatible flange materials, such as stainless steel or carbon steel.
