There have been advancements in the research and development of clean energy sources. Hydrogen has been identified as a potential green energy source.
The HELICOFLEX® seal is a high performance, flexible metal seal that has exceptional compression and elastic recovery properties. This seal is composed of a close wound helical spring surrounded by one or more metal jackets. The spring is designed to have a specific compression resistance. During compression, the resulting specific pressure forces the jacket to yield and fill the flange imperfections while ensuring positive contact with the flange sealing faces. Each coil of the helical spring acts independently and allows the seal to conform to surface irregularities on the flange surface.
HELICOFLEX® design flexibility allows Technetics engineers to customize the seal characteristics to match each unique application.

Pneumatic seals offer the easiest, safest and most effective way of sealing parts that move in relation to one another and need to be connected and disconnected. CEFIL’AIR® seals, which are expanded and retracted by a pneumatic process, feature a patented design that employs advanced elastomers and modern manufacturing techniques to meet the requirements of numerous applications.
BIO-GUARDIAN® SEALS: essential to the medical, pharmaceutical and food industries, the BIO-GUARDIAN® sealing solution prevents bacterial and microbial growth on equipment and materials. The BIO-GUARDIAN® solution can be used in CEFIL’AIR® inflatable seals to meet the needs of demanding hygienic applications.
The ORIGRAF® seal provides a lasting high-performance sealing solution for all industries. It can be specifically designed for extreme thermal & pressure cycles ensuring higher safety in operation while optimizing total cost of ownership.
Unlike flexible graphite cut gaskets, the compression of the ORIGRAF® die-formed seal is limited by a mechanical stop: groove or inner and/or outer ring. In the case of assemblies subject to extreme pressure and/or temperature this design prevents excessive seating stress on the seal during transients.
This reliable and sustainable solution allows the optimization of overall operating costs, increasing the Mean Time Between Failure (MTBF).
ORIGRAF® seals are mainly used in applications servicing the following industries:
The range of applications can be extensive, including:
