Answer 1

A. During installation, MS flareless fittings are normally tightened by turning the nut a specified amount, rather than being torqued.

Step-by-step explanation:

The use of nut in MS flare less fittings was intended for easier Assembly/disassembly because Sometimes, military often wants to change different parts of their vehicles.

If they use torqued, the changes that they made during the process pretty much becomes permanent. This make it harder for them if they want to make some sort of fix or improvement.
