Questions and answers
Which diameter does the olive fit?
8 mm pipe or hose.
What tightens the olive?
The fitting nut or the olive compression screw d-8 M12x1.
How is it different from the GB493 N olive?
GB493 is the standard version. GB493 N is the low version, which fits English-type quick-shut valves and all RVS 8 screw fittings.

Do I need a reinforcing sleeve?
Yes, with soft copper pipe. The AD 8 x 1 sleeve keeps the pipe from collapsing when tightened.
