In medical technology, choosing the right seal is crucial for the safety and functionality of medical devices. Metal seals offer particular advantages, especially when the highest demands for tightness, durability, and sterility are required. They are characterized by their excellent resistance to extreme temperatures, chemicals, and mechanical stress. They are ideal for demanding sealing applications that require durability and safety.

Parker metal seals are available in various designs, including O-ring seals and specially shaped metal profiles. They can be made of stainless steel, nickel alloys, or other biocompatible metals. Depending on the application, these seals can be customized – whether through special surface treatments, coatings, or combination with elastomeric materials for improved sealing properties.

 Standards and conformities:

• ISO 10993 – Biocompatibility
• USP Class VI – Requirements for materials for direct patient contact
• FDA – Approval for use in medical devices
• REACH and RoHS – Compliance regarding hazardous substances

Characteristics and benefits:

• High mechanical strength: Metal seals withstand high pressures and mechanical stress
• Excellent resistance to high temperatures and chemicals
• Durability due to excellent wear resistance
• Sterilizability: Resistance to common sterilization methods such as autoclaving, ethylene oxide, hydrogen peroxide, or gamma radiation
• Biocompatibility: Suitable materials ensure safety during patient contact
• Reusability: Many metal seals can be used multiple times after testing

Typical applications:

• High-pressure and vacuum systems
• Sterilization devices and autoclaves
• Biopharmaceutical production equipment
• Components in surgical instruments
• Medical analysis and diagnostic systems

 Metal seals are the first choice when it comes to robust and durable seals in medical technology. Their combination of mechanical stability and durability makes them indispensable for critical applications.
