Question

line wrench
a line wrench is a special type of wrench designed especially for loosening pipe and cable fitt
resembling a combination between a box-end and open-end wrench. this wrench design gri
the nut on more edges, so you can apply more force to either loosen or tighten.

line wrenches are commonly used to loosen/tighten brake, power steering, transmission/engin
oil cooler line fittings and cable ends. an open end wrench should not be used to initially loosen
these types of connections, because the risk of slipping and damaging the fitting is considerable

why is the use of a line wrench preferable when loosening a brake line fitting?

the line wrench limits the maximum transferable force.
a line wrench prevents snapping off a bolt head.
a line wrench grips the nut more securely; reducing the risk of slipping that causes damage.

Explanation:

To determine the correct answer, we analyze the description of the line wrench. The text states that a line wrench "grips the nut on more edges, so you can apply more force to either loosen or tighten" and that an open - end wrench should not be used initially because of the "risk of slipping and damaging the fitting".

• The first option "The line wrench limits the maximum transferable force" is incorrect. The description says the line wrench allows more force to be applied, not limits it.
• The second option "A line wrench prevents snapping off a bolt head" is not supported by the given text. The text focuses on slipping and damage to the fitting, not on preventing bolt heads from snapping off.
• The third option "A line wrench grips the nut more securely; reducing the risk of slipping that causes damage" matches the information from the text. The line wrench's design of gripping the nut on more edges reduces the risk of slipping (which can cause damage), making it preferable for loosening brake line fittings.

Answer:

A line wrench grips the nut more securely; reducing the risk of slipping that causes damage.
