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.
