Temperature classifications under API 6A directly impact seal material selection and design parameters. Standard temperature classes include K (-75°F to 180°F), L (-50°F to 180°F), P (0°F to 180°F), S (0°F to 250°F), T (0°F to 300°F), and U (0°F to 350°F). Each class requires seal materials capable of maintaining elasticity, compression set resistance, and chemical compatibility throu... https://globalsealstech.com/
