Metallic Gaskets
Durlon® metallic gaskets, particularly their range of Ring Type Joints (RTJs), are highly specialized for use in high-pressure and high-temperature applications typically found in the oil, gas, and petrochemical industries. RTJs are precision-engineered, metallic sealing rings designed to withstand extreme conditions. These gaskets are available in different shapes (such as oval or octagonal cross-sections) and materials, including soft iron, stainless steel, and other alloys, allowing them to be tailored to specific pressures, temperatures, and chemical exposures.

What Are Metallic Gaskets?
Metallic gaskets are sealing components manufactured entirely or primarily from metal materials, designed to create leak-proof connections between flanged joints in high-pressure, high-temperature, or chemically aggressive environments. Unlike non-metallic gaskets made from rubber, PTFE, or fiber materials, metal gasket material provides superior strength, temperature resistance, and long-term durability under extreme operating conditions.
The primary types of metallic gaskets include:
• Ring Type Joints (RTJs): Solid metal rings (oval or octagonal) that seat into grooved flanges, ideal for API 6A and ASME B16.5 applications.
• Spiral Wound Gaskets: Metal strips wound with filler material, combining flexibility with metal strength.
• Kammprofile Gaskets: Serrated metal core with soft facing, excellent for heat exchangers.
• Solid Metal Gaskets: Flat or profiled solid metal rings for extreme pressure service.
Metal gasket materials are selected based on the operating environment. Common materials include:
• Soft Iron: Standard applications, excellent compressibility.
• 304/316 Stainless Steel: Corrosion resistance for chemical service.
• Inconel 625/825: High-temperature and corrosive environments.
• Monel 400: Seawater and marine applications.
• Titanium: Aggressive chemical and high-temperature service.

How RTJ Metallic Gaskets Create a Reliable Seal
The design of Durlon RTJs enables them to seal effectively by concentrating the compressive force of the flange bolts into a small area of the gasket, thereby creating a very tight and durable metal gasket seal. This is essential in preventing leaks in systems that operate under high pressure.
Key sealing advantages of RTJ metallic gaskets:
• Metal-to-metal contact: Eliminates the need for additional sealants that can degrade under extreme conditions.
• Concentrated stress: Bolt load focuses on a narrow sealing surface for maximum compression.
• Self-energizing design: Internal pressure enhances the seal rather than working against it.
• Reusable flanges: RTJ grooves can be reused with new gaskets, reducing maintenance costs.
Additionally, the metal-to-metal contact of the RTJ eliminates the need for additional sealants, which can degrade under extreme conditions, thereby ensuring long-term reliability and safety.
