What units do you understand? If a torque were specified, it would be
difficult to implement - because torque wrenches and open-ended spanners
don't mix very readily.
It's largely a matter of feel. At a certain point, you can feel the olive
being crimped onto the pipe. This is point at which to stop. If you do it up
beyond what is necessary, you'll start to "neck" the pipe - and will have a
less good seal than when it is just right.
Buy a few spare olives, and practice on a few bits of scrap pipe. Take the
joints apart and check that the olives are tight on the pipe without any
necking. Then make a mental note of what it felt like as you tightened it.
An alternative is to use metal push-fits . You just push the (well cleaned)
pipe into the fitting - and Bob's the proverbial! Very handy in confined
spaces where there's not much spanner access.
