I use Liquigas cylinders. Having removed the green safety cap from three full cylinders I was surprised to note three entirely different types of valve set into these cylinders. Needless to say, one can often find it difficult to attach the regulator to the cylinder.
This anomaly begs the question, are the regulators designed to fit all, or is one expected to use a different regulator for each of the different cylinder valves fitted to these cylinders?
Is anyone actually responsible for this state of affairs? Surely there is a health and safety issue here?
