Get a Better Connection with the Right Torque

Reliable industrial connectivity starts with proper installation. If a connector is too loose, it may not seal correctly. If it is overtightened, the connector or mating interface may be damaged. 

A connector torque wrench removes the guesswork by applying a specified amount of torque. 

Why use a torque wrench? 

“Hand-tight” can vary by installer and application. Using the correct torque wrench helps: 

• Produce consistent, repeatable connections 

• Support proper sealing 

• Prevent loose connections 

• Reduce the risk of overtightening 

• Standardize installation and maintenance 

How does a connector torque wrench work? 

A connector torque wrench applies a defined amount of tightening torque to the connector’s coupling nut. The correct tool depends on three criteria: 

• Required torque 

• Connector type 

• Wrench opening 

Always check the connector documentation before selecting the tool. Similar-looking connectors may require different torque values because their materials and design can differ.

How do you use a connector torque wrench? 

Use the following sequence to tighten the connector consistently: 

1. Identify the connector type. 

2. Verify the specified torque in the connector documentation. 

3. Select the correct wrench. 

4. Inspect and align the connection. 

5. Thread the coupling nut by hand. 

6. Apply steady pressure with the torque wrench. 

7. Stop when the wrench indicates that the specified torque has been reached. 

Important: Do not continue tightening after the specified torque has been reached.
