SEAL LOCK® sealing nuts are one-piece structural components.
Sealing against leakage can be executed in the thread or bearing face. These components are used e. g. for hydraulic or pneumatic systems or for fuel systems.
With SEAL LOCK® sealing nuts, high-strength screwed connections can be realised without loss of preload-forces – they can even be used in repeated screwings.
Assembly direction:
The nut is screwed onto the bolt with its sealing ring first.
If assembled from the opposite direction it is critical that the sealing ring is supported.
