LPG Hose & Regulator Assemblies

If your auto regulator is not switching over, we recommend looking at the indicator first.

The indicator at the top of the gas regulator indicates if the gas bottle in use contains gas or is empty.

When the indicator is green, the regulator is ON and the gas bottle in use contains gas. When the indicator is RED, the cylinder it is pointing to is empty and the internal valve has switched over to use the other cylinder.

Please note, the indicator only indicates the contents of the cylinder that it is "pointing to" or "in use".  This means that the indicator can show RED when reading the first empty cylinder, even when the second cylinder has gas and is in use.

To accurately check the regulator/indicator is working – only connect or turn on one cylinder at a time and check if it is green or red and if there is gas at the outlet.

First Stage and Second Stage gas regulators are used in domestic and commercial applications.

A first stage gas regulator is often connected to one or two gas cylinder/s with pigtail/s, taking the pressure from max. 1750kPa to approximately 70kPa. A second stage gas regulator is placed further along the gas line and takes the gas pressure from approximately 70kPa to 2.75kPa.

We recommend Kosan First Stage and Second Stage regulators for high-pressure and high-volume commercial applications.

All Bromic and Cavagna dual-stage regulators come with a patented safety shut-off feature.

The safety shut-off is a mechanism that will engage in the event of gas flow greater than 140% of rated flow (e.g. regulator diaphragm failure, equipment leakage downstream). This prevents any potential emergencies and ensures safety at all times.

Manual changeover and automatic changeover dual-stage gas regulators are used for multi-LPG cylinder setups.

Once one LPG cylinder runs out, an automatic changeover regulator will automatically switch from using one gas cylinder to another. For manual changeover regulators, the user will need to manually reset the valve after the first gas cylinder runs out.

Manual changeover gas regulators mean that you are less likely to unknowingly end up with two empty gas cylinders. However, they mean that you will have to pause gas usage and switch cylinders manually.

Using an automatic changeover gas regulator means that you don’t have to pause gas usage. However, you will need to routinely inspect your set-up to ensure that gas bottles are not empty.

To suit your preferences and needs, Bromic supplies both automatic and manual changeover gas regulators.

Only our appliance regulators are for indoor use. All other gas regulators are for outdoor use only.
