The Brief Introduction to Rubber-Steel Metal Gasket with Support O Ring



In industries that deal with high-pressure and high-temperature applications, maintaining a secure and leak-free seal is critical. The Spiral Wound Gasket with Inner and Outer Ring is a specialized gasket designed to provide exceptional sealing performance in demanding environments. In this product description, we will explore the features and benefits of this gasket, highlighting its construction, functionality, and suitability for various industrial applications.

1. Construction and Design:

The Spiral Wound Gasket with Inner and Outer Ring is constructed using a combination of metallic and non-metallic materials. It consists of a metallic winding strip, typically made of stainless steel, wound in a spiral pattern with a filler material, such as graphite or PTFE (Polytetrafluoroethylene). The inner and outer rings, also made of stainless steel, are placed at the top and bottom of the winding to provide additional structural support and prevent inward and outward buckling.

2. Reliable Sealing Performance:

The spiral winding construction of the gasket allows it to conform and adapt to the irregularities and surface imperfections of the flange faces. This results in a tight and reliable seal, preventing leakage of fluids or gases even under extreme conditions. The combination of the metallic winding strip and the filler material offers excellent resilience, allowing the gasket to maintain its sealing properties over a wide range of pressures and temperatures.

3. Enhanced Stability and Protection:

The inclusion of the inner and outer rings in the Spiral Wound Gasket provides enhanced stability and protection. The inner ring helps to center the gasket within the flange, ensuring proper alignment and preventing the gasket from being pushed out of place during installation or operation. The outer ring acts as a barrier, shielding the winding and filler material from external factors such as abrasion, impact, and fluctuating temperatures, extending the gasket's service life and reliability.

4. Versatility in Application:

The Spiral Wound Gasket with Inner and Outer Ring is suitable for a wide range of industrial applications. It is commonly used in pipelines, pressure vessels, heat exchangers, pumps, and other equipment that require a high-integrity sealing solution. The gasket is designed to handle various media, including steam, oil, gas, chemicals, and hydrocarbons. Its versatility allows it to be used in industries such as oil and gas, petrochemicals, power generation, chemical processing, and more.

5. Compliance with Industry Standards:

The Spiral Wound Gasket with Inner and Outer Ring is manufactured to meet industry standards and specifications. It undergoes rigorous testing to ensure it meets the required performance criteria for pressure, temperature, and chemical compatibility. This commitment to quality and compliance ensures that the gasket performs reliably and consistently in demanding industrial environments.

6. Installation and Maintenance:

Installing and maintaining the Spiral Wound Gasket with Inner and Outer Ring is straightforward. The gasket is typically installed between two flange faces, with the inner and outer rings positioned correctly. Proper installation techniques, including bolt torqueing and flange alignment, ensure optimal performance and longevity. Regular inspection and replacement of gaskets as needed help maintain the integrity of the sealing system and prevent potential leaks.


The Spiral Wound Gasket with Inner and Outer Ring offers reliable sealing performance and durability in high-pressure and high-temperature applications. Its spiral winding construction, combined with the inner and outer rings, provides a secure and leak-free seal, even in challenging industrial environments. With its versatility, compliance with industry standards, and ease of installation, this gasket is an essential component in ensuring the integrity and safety of piping systems and equipment.
