Screw seals are used as static seals for screw connections and flange seals, for example in mechanical engineering, container and apparatus construction.
Advantages of screw seal:
- Simple and captive installation - Secure seal - Reusable - Fixation through internal centering - Cost-effective solution - Controlled pressing through the metal disc - Available in different metal versions - Available for almost all European thread sizes
Other elastomer qualities such as EPDM, HNBR and FVMQ are available upon request
