@mushishi With that particular adapter sure, If you notice the metal valve at the one end it looks like they installed a poor mans (pressure regulator) .
Thats probably 12 dollars in parts for $100 dollars.
As long as the hose itself is designed for pressure you'd probably be better off buying a "real" pressure regulator, the soda stream adapter and a length of hose. That way you can accurately read the pressure in your tank and detect any potential leaks.
C02 pressured hoses seem pretty cheap.

Basically that product you linked will work and won't leak but the same can be said about a hose and adapter you assemble yourself as long as you place a regulator before the hose even if you go the poor mans route like they did.
