Gas regulator - How It Works

How to Replace: BBQ Grill Hose  & 




A regulator, LPG connector, BBQ hose, propane regulator or most commonly known as the grill hose is a device used to control or regulate the amount of gas flowing towards the grill plates or burners (surface area where you cook food)
















The regulator is usually connected close to the top of the hose, is silver in color and near to the shut-of control valve over the propane tank or gas cylinder.


The propane regulator is a simple robust device but can be  prone to damage from excessive temperature changes (if you leave your BBQ outside). I've also heard of insects entering the hose and regulator. Sometimes things just fail. Personally, my hose damage was done by animals chewing the hose and the regulator was okay.


Either a damaged or faulty regulator will block the flow of gas towards the grill. Clearly that will effect  how your grill will cook and operate! 


In some cases, a bypass valve inside the regulator may also get stuck stopping the gas from exiting the tank altogether.


All these scenarios call for a quick and easy replacement of that regulator. 


The regulator also acts as barrier blocking blow-back of the flames from your grill. A safety device to simply stop flames reaching back to propane tank through the hose. In the modern grills all connector hoses come attached to the regulator.


Any leak, cuts, excessive stiffness due to harsh weather can or an animal is a serious hazard. Lives are lost every year and millions of dollars of property damage happens because of BBQ fires. Again, serious and life threatening !


It goes without saying, if you smell gas... shut off and disconnect from the tank. DO NOT USE YOUR GRILL!


In that case, the whole assembly (regulator kit) containing the regulator and connecting hose needs to be replaced. In most of the gas grills, regulator is tightened over the shut-off or control valve located on the upper side of the propane tank and has a round shape that turns both clockwise and anti-clockwise.


A step-by-step guide on the installation or replacement of the modern propane regulator kit with a combined connecting hose is discussed below:














Step-1: Start with turning off the flow of gas from the propane tank by turning the shut-off valve over the tank clockwise. In order to make sure it is completely turned off and no gas is leaking, turn the knob to the extreme end as far as it can go.



Step-2: Disconnect the connector hose, which is attached to the burner assembly of the gas grill. Use an adjustable wrench for unscrewing the mounting nut usually made up of brass and hexagonal shaped connected over the hose edge and burner connection. Do not pull it or apply force as the burner connection may get damaged. 











Step-3: After the grill side is disconnected, unscrew the regulator side from the propane tank. There is no need for wrench as it can easily come off by firmly griping and then turning the knurled knob on the regulator in the anti-clockwise direction. 



Step-4: Search our GRILL HOSE FINDER and locate your replacement hose. Next day delivery available from


For old gas grills, you need to buy an extra fitting too, which is connected on the burner connection and then easily houses the modern regulators.



In addition, we recommend Teflon tape especially for older grill connections. It improves the seal.









Step-5: Connect the regulator to the control valve on the propane tank or gas cylinder by simply turning the knurled knob clockwise and making sure it’s tight enough to protect any leakage. 


Step-6: For connecting the other side of the regulator or the connector hose, first wrap the burner connection with Teflon tape. After it’s wrapped, screw the brass mounted nut of the connector hose over it and tighten it with the help of wrench. 


The replacement or installation of the propane regulator is complete. However to make sure everything is tight enough and there is no leakage, first turn on the control valve located over the propane tank. Once the gas flow starts, use a soapy water and pour it with the help of a brush over all the connections i.e. burner connection, regulator and the control valve too. If bubbles appear over the soapy water, check all the connections again and tight them a bit more. 













Frequently Asked Questions:


How often should I replace my regulator or connector hose?

There is not any specific time for replacement as good quality regulators can last up to 5 years or even 10 in some cases. Rust on the regulator, damaged or leaked connector hose and changes in pressure level of the propane gas are a few signs it's time buy a replacement grill hose kit!


Why are the flame levels on my gas grill lower than normal?


If the flames on your gas grill are low even if on full blast, then there is clearly issues with the propane regulator, faulty control valve over the propane tank, leakage in the hose or in the burner connection. 

Time to do an inspection of the hose and that's probably were the issue is.


How do I know if the propane regulator is faulty?


A fault in the regulator or the bypass valve inside the regulator will result in either too high or too pressure in the gas flow. It can be observed and is evident through the flame levels on the grill when operating.


If there is physical damage then soapy water will bubble when put on the hose and regulator.













Is it okay storing my propane tank indoor?

No. It is highly recommended to keep the propane tank outdoors in an open space and on a leveled surface.


How do I disconnect propane tank from the BBQ grill?

Firstly, turn off the control or shut-off valve located on the top of the propane tank. Unscrew a hexagonal brass nut located near the burner and on one side of the gas hose. Once the nut is unscrewed, the disconnection is successful.


How do I test if there is any leakage of gas near my BBQ grill?

Use a soapy water to wipe all the connections with the help of a brush. This includes the burner and hose connection, control value and propane tank connection and the regulator connection. In addition, wipe the connector hose too as any small cut in it can lead to a leakage. Bubbles emerging through the soapy water are an indication of the gas leakage.


What tools do I need for replacing a connector hose or regulator of my gas grill?

Replacing a connector hose or the regulator is not so complex. Any homeowner or person having the physical ability to unscrew a nut can do it.


An adjustable wrench and optional Teflon tape can do the work, however, a vice-grip is also a good tool if the connector hose or the burner connections are sticky and you are finding it difficult to unscrew some nuts.
