Can I connect a GAS IT bottle and GAS IT tank together?

There is technically no limit to the number of GAS IT bottles or GAS IT tanks that you can can connect together from 1 fill point so they all fill together (  you can also mix and match GAS IT bottles and GAS IT tanks together as well ).

In fact you can also connect more than 1 fill point to a GAS IT bottle or tank system. So imagine a large RV where you could have 2 fill points to your refillable GAS IT system so you can fill from opposite sides of a vehicle for example.

All you need to do is make sure you have the right number of connection tees and hoses to connect them together.

It's also with noting that you can mix and match any size of GAS IT bottle or GAS IT tank together as 1 fill system, so you can have a 6kg and an 11kg for example, or a 11kg bottle and a 160 ltr GAS IT tank.
