Mechanical seals with PTFE rings are versatile components widely adopted across industries due to PTFE's exceptional chemical resistance, temperature stability, and low friction properties. These seals are critical in environments demanding reliability under harsh conditions, from aggressive chemical processing to sterile medical applications. Their usage spans sectors where contamination prevention, durability, and precision sealing are paramount, such as oil and gas extraction, aerospace systems, and food production lines. The material's biocompatibility also makes it indispensable in medical devices and pharmaceutical manufacturing.
Key Points Explained:
