When proven engineering and unrivaled reliability matter, Technetics Group metal seals make a difference. Our unique metal seal sealing solutions deliver high performance even in the most challenging conditions. At Technetics Group, our metal seals are specifically designed to utilize the elements of force, fluid and pressure to assist in their solution of sealing.

About Technetics Group Metal Seals

Technetics Group metal seals come in an endless variety of options, although the majority are static seals—seals that function much like a gasket between two flanges that have little or no relative motion. Our metal seal sealing solutions, available ready-made and custom-engineered, are designed to maximize performance and optimizing the assembly.

Product Features

Properties and Technical Information

  • Available in a Variety of Sizes
    While many of our seals come in a nearly infinite number of sizes, including up to 7 meters in diameter, typically they are from 1/8″ to >100″ (3.175mm to 2,540mm).
  • Extreme Temperature Performance
    Performs in a wide range of temperatures, from -423˚F to 1450°F (-253°C to 788°C).
  • Customized
    The majority of Technetics Group’s metallic seal sealing solutions are custom-engineered. Our equipment designers are experienced in meeting all specific requirements while maximizing performance and minimizing weight. The work benefits from our close partnerships with leading industry OEMs, and our long-standing relationships with government research agencies, renowned universities, independent research firms, and national laboratories.
  • Tested and Proven
    Our design concepts are rigorously tested with state-of-the-art design software and testing equipment to replicate performance under critical operating environments.
