Advantages of SEAL LOCK®

Seal
Double sealing action. SEAL LOCK® seals simultaneously inside the thread and below the head against liquids and gas.
High preload force
The metal coating prevents a loss of preload force when the sealing ring is installed.
Resistance
The temperature resistance of SEAL LOCK® sealing nuts is -40 °C to 110 °C.

Method and principle

The reliable solution for sealing a bolt-nut thread

SEAL LOCK® sealing nuts are one-piece structural elements. Sealing against leakage is provided in both the thread and the bearing face. SEAL LOCK® sealing nuts provide a high-strength threaded connection with no loss of preload force – even after repeated screw fastenings.
