Why can the air conditioning connection be made of copper tube? How about rubber tube and aluminium pipe? Please heroes pointing for the dishes.
Rubber tube pressure tube not Yi Nai, welding pressure is relatively low.
The pressure of the aluminum pipe is relatively small. "Again, when the aluminum pipe is too soft, it is easy to be flattened.".. Rubber tubes will decay if they are used! Withstand pressure is also high!
In fact, aluminum can, such as the refrigerator evaporator is aluminum, not only with the hose, the hardness is not enough in fact even the refrigerator either with brass or aluminum, for a long time or leakage, so you can not use the hose. The aluminum tube in the fridge is the easiest place to leak
