SEAL LOCK® Sealing nuts for high-strength screw joints

SEAL LOCK® sealing nuts High-strength connection and maximum sealing Can you imagine high-quality products without screw connections? Modern technology cannot do without them as detachable joints. In the industrial sector, fluid technology, pneumatics and sealing technology are among the fields of application. In those sectors, often additional functions such as sealing, insulation or reuse of bolts are required – only to mention a few. One classic example are adjusting screws on hydraulic components, steering boxes and fuel injection pumps. For those applications, high-strength screw connections...
