The term 'regulator' is usually used in the grill world to describe the gas grill regulators, hoses and fittings that bring gas from your LP tank and connects it to your grill.
With competitive price and timely delivery, ABYDA sincerely hope to be your supplier and partner.
Technically, the regulator is the silver colored disc part that looks like this:
The hose connects it to the brass fitting which is the part that screws onto your grill. Right next to the regulator is a collar that twists freely. That's the part that screws onto the LP tank. Though you should always turn off your LP tank when you're done cooking or when you're changing the regulator, LP tanks are made with an automatic shut off valve. It will only work when a regulator hose is connected to it.
WHY? Regulators, for safety reasons, close down slowly over time as they 'go bad.' You probably won't notice one day your grill is perfect and the next it doesn't light at all. The burner closest to the source of gas will light up better than those farther down the manifold. Your grill will get to lower and lower temperatures over time, even on 'high' heat. The main indicator of needing a new regulator is low heat or low flames, especially if it's getting worse over time.
Keep in mind that you may also have a problem running along the hose. Be aware of the smell of gas even when your grill is off or a tiny hissing sound.
Some animals like to chew on the sun-baked rubber hoses. (Don't knock it 'til you try it?) If this is a problem for you, they have invented handy-dandy hose guards. Check them out.
If you think there's a leak, but you're not sure, you can check the hose with some very soapy water. Rub the suds all the way along the line of the hose. Turn on the gas tank. If there is gas escaping, it will cause the soapy water to bubble at the point of the leak.
A single-hosed, standard regulator is the most commonly used part on grills. It's the picture I used above. These regulators let out up to 60,000 BTUs of gas.
If you have a side burner, check out this dual-hosed standard regulator. There is one regulator (remember that's the disc) and there are two separate hoses. Sometimes one hose comes off the regulator and splits into two hoses, forming a Y shape, and sometimes there are two hoses coming directly out of the regulator itself. Either will work and they are interchangeable.
Updated June : Many of our gas grill regulators now support high-flow needs (let out up to 90,000 BTUs of gas). These are compatible with grills that originally used a standard flow. However, please note that your high setting might give you more heat than before. Pay attention the first time you grill with a new regulator and take note of the cook temps!
Usually, the removal and visual inspection of your regulator determines which replacement you need. It's also a good idea to measure the existing hose and/or the space a hose needs to stretch to reach from the tank to the valve or manifold. If you're not sure, call 678-272-. The staff at GrillPartsSearch.com is always happy to help.
Keep in mind, a standard regulator and hose will not work if you have:
Here's a picture of the fitting:
You can't measure the 3/8.' It's confusing, I know. Like I said, check for a 5/8' measurement.
The good news is that this can be the easiest, cheapest part of your grill to fix!
Remember, not all regulators are created equal. Lower quality rubber will degrade and break more easily in the sun. A lower quality regulator can go bad more quickly.

Is there a difference between LP and natural gas regulators?
Propane regulators and natural gas regulators are not interchangeable, though they both operate in the same fashion. A natural gas regulator is comprised of five components: set screw, spring, rod, diaphragm and valve.
Are all pressure regulators the same?
Are All Gas Grill Regulators the Same? Every propane gas grill uses an LP regulator, but not all regulators are created equal. Though the purpose is the same, different types of setups require different types of regulators. The type of regulator a grill needs is based on the specific propane application requirements.
Are propane and LPG regulators the same?
Please note that Propane gas cylinders contain considerably greater pressure than Butane cylinders and as a result, regulators are designed for use with either Propane or Butane and are not interchangeable because of their different design pressures and the different connections on the cylinder itself.
Can I use any gas regulator?
Each regulator is designed to fit a specific type of cylinder valve and a regulator that fits one type of valve will not fit any of the others. The valve on Propane cylinders has a screw thread and only accommodates Propane regulators.
How many PSI is a gas grill regulator?
How many PSI is a BBQ regulator? Generally, propane pressure should be between 100 and 200 psi ensures that the liquid propane gas remains in a liquid state.
Are Calor Gas and flogas propane regulators the same?
A. Both Calor and FLOGAS clip-on regulators are low-pressure 21mm. and fully interchangeable.
What regulator do I need for propane?
For your propane tank with fill valve, you most likely need the Camco Horizontal 2-Stage Propane Regulator w/ P.O.L ' 160,000 Btu/Hr # CAM. This will have the 1/4 inch NPt inlet and the 3/8 NPT outlet and will maintain a constant 11 inch water column propane pressure for your vent-less heater.
Can you use butane instead of propane?
The company is the world’s best Low Pressure Regulator Gas supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
Can I switch from Butane to Propane? ' Propane operates at a higher pressure than Butane so it is not possible to use a butane regulator on a propane cylinder and vice versa.
Pressure Regulators ' Design Principles, Types and applications
Pressure regulators, in various forms, are used in many domestic and industrial applications, like regulating propane used in gas grills, to regulate oxygen in healthcare equipment, to supply compressed air in industrial applications, to regulate fuel in automotive engines and aerospace applications. The main aspect that is common across all these applications is pressure control ' from a higher source pressure to a lower output pressure.
Spring loaded poppet valves are commonly used as a pressure reducing element. Poppet valves have elastomeric sealing in regular applications and a thermoplastic sealing in high pressure applications. This seals the valve seating against any gas or fluid leakage. The poppet valve is controlled by the spring force to open the valve and let the medium flow from inlet to outlet. As there is a rise in output pressure, the poppet valve closes due to the force generated by the sensing element, which overcomes the spring force.
Pistons are normally used for high pressures, rugged applications and applications where wider tolerances on the outlet pressure are acceptable. They tend to be sluggish due to friction between the pinion sealing and regulator body.
For higher accuracy, a diaphragm type of sensing element is suitable. They are made of elastomer or a thin disc type of material which is sensitive to changes in pressure. Diaphragms tend to have lower friction than piston type designs. They also provide a higher sensing area, for a given regulator size.
Pressure and Gas Type
The two LPGes, Butane and Propane, are very similar, and consequently many domestic appliances (e.g. most domestic cookers) are designed to run on either gas, but the standard supply pressure is somewhat different for each gas to accommodate the differences in the characteristics of the two gases. In the case of Butane, the standard supply pressure is 28 mbar (11" water gauge) and for Propane it is 37 mbar (14" water gauge) - regulators that supply either of these pressures are called "low pressure regulators". The appliance itself will have a badge on it identifying what gas and what pressure it is designed for. There are some appliances (not many) designed to work on considerably higher pressures and these use "high pressure regulators", and again these are clearly marked with what gas and what pressure they are designed for.
Each regulator is designed to fit a specific type of cylinder valve and a regulator that fits one type of valve will not fit any of the others. The valve on Propane cylinders has a screw thread and only accommodates Propane regulators.
Butane is supplied by Flogas under two brands, Flogas and Ergas. The Flogas Butane cylinders are yellow and always use a "Jumbo" valve. There are two types of Ergas Butane cylinders: the orange ones have the same "Jumbo" valve as the Flogas cylinders, but the blue/green cylinders have a much narrower "Compact" valve.
High-pressure regulators have a much narrower nozzle than that fitted to low-pressure regulators and use a much narrower hose (see picture below).
Gas Cylinder Regulators
Regulators must be subject to regular inspection and replaced every 5 year for non-corrosive gases.
The body of the regulator is stamped for date of manufacture
. More frequent replacement cycles are required for corrosive gases.Where a regulator performs the function of 'flow control' and is not regarded as the primary Protective Device, then it will not be regarded as Primary Regualtor and hence will not subject to the 5 year replacement requirement.
Regulators are designed for a specific type of gas ' the correct regulator delivering the correct pressure range must be used on the cylinder.
Pressure Regulators: Do I need one?
US Nitrogen Standards
Since May of , our instruments have been designed and engineered to connect directly to a 207 bar/ psi cylinder. If you bought your instrument prior to this date, the instrument was designed for a US Standard Nitrogen Cylinder. This cylinder is normally delivered with PSI / 173 Bar pressure or less. You should never need a regulator when operating with either system inside the USA using standard 173 bar service.
Nitrogen Cylinders Outside USA
Since May of our instruments have been designed and engineered to connect directly to a 207 bar / psi cylinder. This change was made largely to eliminate the need for a Pressure Regulator. For instruments purchased prior to May of being used outside of the United States, you should consult your local gas supply (nitrogen) store. Check the local requirements for the use and standards of high pressure gas. A regulator will be needed if the tank pressure is greater than 173 Bar/ PSI.
Our instruments come with a 6-Foot Filling Hose fitted with a CGA-580 Nitrogen connection (standard for USA) at the end of the hose. Every country has different requirements and possibly different fittings. You may need to buy an adaptor or change the nitrogen fitting for service in your area. We might carry your local fitting in stock. Please contact us directly to check if we carry your nitrogen fitting.
If you need a regulator, there are two types. The first is a High Pressure Regulator with a Supply Pressure of 200 Bar and Delivery Pressure of 0-100 Bar. This type of regulator is designed to be connected directly to your local gas tank (pressure no higher than 207 Bar) and then connected directly to the instrument. The regulator allows you to adjust the pressure to the operating pressure of the Pressure Chamber. We can help modify your 6-Foot Hose to connect to the instrument directly.
The second type of High Pressure Regulator has a Supply Pressure of 200 Bar and Delivery Pressure of 0-173 Bar. This type of regulator is designed to connect to your local tank and trans-fill into one of our Portable Tanks or the internal tank of the Model 610 or Model 615. This regulator is only used during the trans-filling of the tank.
