gas-tight = gas + tight (transparent) = gas + tight

Compound of 'gas' + 'tight' whose meaning ('not allowing gas to pass') follows directly from the components.

Etymology

Gas-tight is a simple compound of gas and tight. Imagine a jar with its lid pressed down so no air or smell can get out; 'tight' here means 'completely closed', so something gas-tight stops gas from escaping.
