GasStop emergency shut-off gas safety valve

GasStop is an easy-to-install smart emergency gas shut-off valve that immediately closes off your gas system in the event of a major gas leak.

This must-have safety device can be used on bottled and portable Propane gas systems that use the UK-POL fitting (Calor Propane bottles for example)

GasStop can be used to test for slow leaks before and features a handy pressure gauge that indicates when you are low on gas.

This small, easy-to-fit safety device can help eliminate hazardous gas leaks for caravans, motorhomes, campervans, boats, BBQs, and when camping.

Each GasStop comes with a five-year warranty and is fully tested to British and European standards.

How can GasStop differentiate between a major and a minor leak?

GasStop will only shut off in the event of a major leak. A major leak is defined as a sudden and dramatic change in the gas flow rate. GasStop is calibrated to shut off at ≥110% of the guaranteed flow rate (EN 16129:2013).

If GasStop was calibrated to shut off in the event of a minor leak, this would interfere with the 'normal' usage/consumption of your gas appliance(s) and your gas supply would be shut off each time your appliances were used.

EU standards state that an LPG shut-off device must be calibrated as described above.

A slow leak, or normal consumption, does not cause the device to shut off. But, GasStop can be used to test for minor leaks in the system before use. To do this, you "close" off the system by turning off all appliances and heating, then any drop in pressure will be picked up on the gauge.
