PTFE ring gaskets are sealing components designed to create a reliable and leak-free seal in flanged connections. PTFE ring 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 ring gaskets provide a reliable seal between two flange surfaces, preventing leakage of fluids or gases. The soft and conformable nature of PTFE allows the gasket to conform to the flange faces, filling irregularities and creating a tight seal.
PTFE ring 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 ring 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 low coefficient of friction, resulting in reduced wear and minimizing the risk of galling or sticking. This property allows for easy installation and removal of the gasket and helps to prevent damage to the flange faces during assembly.
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 ring 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.
