The 100 Series helical spring design is intended for static applications due to the high unit load. It can be used in very slow or infrequent dynamic conditions when friction and wear are secondary concerns to positive sealing. The 100 Series seal design produces an evenly distributed load across each individual band. Polymer Concepts' manufacturing maintains minimal gaps between coils. This tight spacing provides continuous load, reducing potential leak paths. This tight spacing, combined with high unit load, makes this series well suited for vacuum and cryogenic applications.
Our Helical Spring Seals are designed to fit your hardware's orientation, diameter, geometry, and size. Each Helical Spring Seal is engineered to your design’s application requirements. All of our Helical Spring Seals share common characteristics among cross sections. Below is a sample of our most common designs.
