Find high strength hoses and low pressure regulators to connect the LPG bottle safely to your gas device.
The necessary accessory to securely connect a gas appliance to the bottle is the pressure regulator. The regulators are used to reduce the gas pressure of your LPG bottle and maintain the pressure at steady levels, within the acceptable limits, making it suitable for your gas device.
Depending on the device and the LPG bottle you want to connect your device, there are 2 types of controllers: screws and the special "Bayonet" (or "One Click") that make the connection playful, no need for muscle or tools and flanges for changing the LPG bottle.
Check out the barbecue maker's instructions and obtain the right regulator and hose that suits your own barbecue.
