Backup wrenches are used?

To install fittings
To prevent damage to propane connections
To improve grip
To adjust valves

The correct answer is: To prevent damage to propane connections

Backup wrenches are specifically designed to prevent damage to connections, particularly in situations where excessive torque could lead to deformation or stress on the fittings. When working with propane connections, it's vital to apply the correct amount of force without compromising the integrity of the components. By using a backup wrench, the technician can stabilize the connection while loosening or tightening fittings with a primary wrench, ensuring that the connection remains intact and secure without being over-stressed. Using a backup wrench in this context helps to support the fitting and prevent it from turning or bending, protecting both the fitting and the connected component from potential damage. Other functions such as installing fittings, improving grip, or adjusting valves do not specifically pertain to the primary purpose of a backup wrench, which is to safeguard against damage during maintenance or installation tasks.
