The GasStop protects against any gas leaks in your vehicle, by automatically shutting off the supply as soon as a major leak is detected. It also has a test function to let you check for any minor leaks, along with having a built-in pressure gauge.
One device – multiple uses
Please note that this only works on Propane bottles.
It will work in conjunction with both bottle top type regulators as shown in the image, or with bulkhead regulators and the pigtail hose to the bottle.
The Gasstop is always screwed onto the bottle first, as this will protect against a leak before or after the regulator
* What does Gasstop define as a major leak?
GasStop will only shut-off in the event of a major leak, not a slow/minor leak. GasStop is calibrated to offer major leak protection while allowing the operator to use their low pressure propane system as expected under normal working conditions. To achieve this balance between protection and operating convenience, a major leak is defined as a sudden and dramatic change in the gas flow rate equivalent to a flow rate of 33 litres per minute (l/min) or more. A real world example of a “sudden and dramatic change in the gas flow” is the complete and immediate rupture of a propane hose during a fire or tire blowout. GasStop is also calibrated to shut-off at ≥125% of the guaranteed flow rate (EN requirement).
If GasStop were to be calibrated to shut-off in the event of a minor leak, this would interfere with the ‘normal’ usage/consumption of your gas appliance(s) – GasStop would shut-off every time you use your appliance(s). We have therefore calibrated the device to shut-off for major leaks only.
EN standards state that an LPG shut-off device must be calibrated as described above. GasStop will therefore not shut-off the supply of gas in the event of a minor leak.
