SEAL LOCK® sealing nuts are one-piece structural elements. Sealing against leakage is possible in the thread as well in the bearing face. Moreover, SEAL LOCK® sealing nuts provide a high-strength threaded connection with no loss of preload force – even with repeat screw fastenings.
Applications
SEAL LOCK® sealing nuts are used for example in hydraulic control systems for sealing and locking adjusting screws in the return chamber of a directional control valve block. Additionally, they can be used for locking setscrews on the pressure-relief valve of internal gear pumps or for sealing and locking on the control lever shaft of the flow regulator for aircraft refuelling systems.
