How often can 37 deg flare fittings be disassembled and reassembled?

For example LOX -16  duct to ball valve or TC (thrust chamber)?

Does the male mating surface on the valve or TC wear to the point of not 
getting reliable seals?

Are there problems using aluminum tube?   with stainless hardware?

What's a good flare reference source?

Swagelok has limited break/make capability.
