A. light flexible hose
B. heavy duty rubber gauge line
C. copper tube
D. garden hose and gauge set



Answer :

Final answer:

The best material for connecting lines to a vacuum pump for accurate testing is thick-walled rubber tubing. Copper wire can be used to secure hose attachments and avoid leaks due to changes in water pressure. Avoid bending or straining the tubing to prevent leaks in the system.


Explanation:

The best material to use for connecting lines to a vacuum pump for accurate testing is thick-walled rubber tubing. This type of tubing is recommended to prevent leaks in the system and ensure proper vacuum seal.

Using copper wire to secure the hose attachments to the condenser is also suggested, especially if the setup will be unattended for an extended period of time, to prevent leaks due to changes in water pressure.

Additionally, it is crucial to not bend or strain the tubing excessively to avoid creating potential leaks in the system.
