Why 8.5kg and 3.7kg Refills?

There are many LPG bottles that are labelled as 9kg or 4kg that are actually manufactured undersize, with less than the labelled capacity.

This is a result of the manufacturing and design variances amongst the many manufacturers.

To take into account these cylinder size variations, refills were standardised on 8.5kg and 3.7kg.

This allows for the size variances between bottles and prevents any unsafe overfilling.

To make sure that consumers are fully informed, the bottles are labelled accordingly.
