Both the size of the gas test gauge you require and the type of hose your tool will need will depend upon the type of gas being tested; natural gas or liquefied petroleum gas (LPG). Natural gas is more commonly used for heating and cooking purposes, as it is directly delivered to properties through gas pipelines from the national gas network.
On the other hand, LPG is less common. It is stored in large pressurised tanks and used as an alternative when it is not possible to access piped natural gas. |

Size (capacity) |
||||
 |
Gas test gauges are available in a range of different sizes.
For checking the pressure of appliances that use natural gas, a 300mm (11.8″) gauge capable of measuring up to 30 mbar is suitable. This is because the pressure of domestic natural gas is less than 30 mbar. |

However if you are testing LPG, a gas with a greater pressure, you will need a much larger gas test gauge.
Gauges that are 600mm (23.6″) or 900mm (35.4″) long and capable of measuring up to 60 or 90 mbar are used for testing LPG systems. |

Hose |

 |
The type of gas being tested is also very important in determining what kind of hose you will need for your gas test gauge.
For natural gas, most rubber hoses are suitable. However, if you are checking the pressure of LPG appliances, you will need a hose made out of nitrile or neoprene, materials that are resistant to liquefied petroleum gas. |
