Understanding Torque values is crucial to your connectors design. Properly applied torque can make the difference for a sealed connection.

We have provided charts with general information regarding application level for torque specifications.

Please note the differences in thread types and the Hex Nut materials that are used.

Different thread types can have the same material but yield a different torque spec.

For torque specs not included, Contact Technical Support.
