If that coper then you need to know two things ( my dad was doing airco for 32y) , you have 2 basic types , we can call soft tube DVP1-Cu and they can be bended easy even with hands most of time for fridge repair,car etc and then you have .. we calling ''hardened'' tube DNP-Cu and they need big radius and they are used for straight long line. Good bender is not making tube flat and pushing side inside to prevent of flat spot. About sand : try and im sure that you will snap tube , you need to know exactly how much of sand you can fill inside. We bending with pre-heating , 2x end cap with low pressure 1-4.5 psi .
i hope that helps..
