Why Choose ORIGRAF® Expanded Graphite Seals from Technetics Group? 

ORIGRAF® die-formed expanded graphite seals are engineered to deliver exceptional sealing performance in the most demanding environments—where conventional solutions often fall short. 

Unlike standard graphite gaskets or competitor expanded graphite seals, ORIGRAF® seals offer superior adaptability and resilience. Thanks to our proprietary manufacturing process, the graphite structure maintains flexibility, allowing the seal to conform to surface irregularities—even under offloading or transient conditions. This ensures consistent, leak-tight performance where others may fail. 

What Makes ORIGRAF® Stand Out? 

  • Kontrollierte Kompression
    Unlike flexible graphite cut gaskets or spiral-wound gaskets, ORIGRAF® seals are designed with mechanical stops—such as precision-engineered grooves or inner/outer rings—that limit compression. This prevents overloading and protects the seal during thermal and pressure fluctuations. 
  • Superior Stress Management – Built for Critical Applications
    The design minimizes excessive seating stress, preserving seal integrity and extending service life in during transient when assemblies are subject to high-pressure, high-temperature environments. ORIGRAF® seals are trusted in industries where safety, reliability, and performance are non-negotiable—from energy and chemical processing to aerospace and defense. 

Choose ORIGRAF® for a smarter, safer, and more cost-effective sealing solution—engineered to reduce maintenance, improve operational safety, and lower your total cost of ownership.

Key Features of ORIGRAF® Expanded Graphite Seals 

Engineered for performance in the most demanding environments, ORIGRAF® expanded graphite seals offer a unique combination of resilience, adaptability, and ease of use: 

  • Außergewöhnlich elastische Erholung
    Achieves up to 40% compression recovery, delivering a reliable spring-back effect for long-term sealing performance (Characterized in our MAESTRAL Laboratory). 
  • Geringes Kriechen und Entspannen
    Maintains dimensional stability under critical pressures and temperatures, reducing the need for retightening. 
  • Strahlen- und Chemikalienbeständigkeit
    Ideal for nuclear and chemical processing applications, with excellent resistance to harsh media and radiation exposure (Specific nuclear graphite grades on request – for instance PMUC). 
  • Thermische und druckbedingte Anpassungsfähigkeit
    Performs reliably under extreme temperature and pressure fluctuations, ensuring consistent sealing in transient conditions. 
  • Metall-auf-Metall-Kontaktdesign
    Enhances structural strength and ensures consistent seating load control. 
  • Unempfindlich gegen asymmetrisches Anziehen der Schrauben
    Maintains sealing performance even when assembly torque is uneven—reducing installation errors and improving reliability. 
  • Non-Adhesive to the Flanges Contact Surfaces
    Klebt in der Regel nicht an den Flanschen, was ein schnelles und beschädigungsfreies Entfernen und Auswechseln bei Wartungsarbeiten ermöglicht.
