O-Ring Materials Compared: How to Choose the Right Seal for Extreme Environments
Selecting the correct O-ring material for extreme environments requires balancing thermal stability, chemical compatibility, and mechanical pressure limits. In high-temperature or aggressive chemical applications, Fluorocarbon (Viton/FKM) is the industry standard up to 200°C, while Silicone (VMQ) excels in extreme thermal swings (-60°C to +250°C). For standard hydraulic or petroleum...
