The spud orifice is a male fitting (see far left picture) that will screw into the valve where as the hood orifice (see far right picture) is a female fitting that will screw onto the male valve end (see far right picture). You cannot operate a gas grill without an orifice.
What is the difference between a Spud and Hood orifice?
The spud orifice is a male fitting that’ll screw into the valve, while the hood orifice is a female fitting that will screw into the male valve end of the valve. A gas grill can’t be used without the presence of an aperture. What Does Orifice Size Mean? The operating pressure of your machine is determined by the size of the aperture of the nozzle.

What are the standards for sizing orifices?
The American Gas Association (AGA), the American Petroleum Institute (API), and the International Organization for Standardization (ISO) has created standards for sizing orifices (ISO). Orifice plate meters are used in a wide variety of environments and flow ranges, typically under difficult circumstances.
What is a spud on a gas cooktop?
For most gas cooktops a threaded brass orifice or "spud" is used to meter gas at the proper flow rate at each burner. Gas flow rate, a combination of supply pressure and orifice diameter, determines the quantity of gas available at the individual burner and thus sets its BTU output rate or range.
What is an orifice on a gas stove?
The gas orifice dispenses fuel into the combustion or burner tube through a small, high precision hole. The orifice delivers just the right amount of fuel to mix with the correct amount of air, to create just the right flame for the job in your appliance.

What does a orifice look like?
The orifice looks like a tiny brass cup. This is the orifice up close. You can see how tiny the hole in the center is. Hold it up to a light and look through it.
Do you need an orifice for natural gas?
Propane and Natural Gas Are Supplied at Different Pressures Cooktop burners typically supply about 40,000 BTUs per hour. A propane stove orifice size is about 0.082 inches (drill size 45), but the valve on a similar stove that uses natural gas needs an orifice that is almost 0.125 inches (drill size 35).

What does an orifice do?
Orifice plates are a primary flow element, detecting the flow of a fluid passing through the plate by sensing the pressure drop across the plate. When a fluid flows through a restriction in a pipe, it creates a pressure difference between upstream and downstream of the restriction.
What does an orifice tube look like?

Can AC run without orifice tube?
Faulty orifice tubes can also result in too little refrigerant flow through the evaporator. If this is the case, the flow of refrigerant will not be enough to absorb the heat that is coming from the condenser. When this occurs, the A/C simply will not be performing well enough to allow the system to cool.

What size hole is in a natural gas orifice?
Natural gas pilot orifice sizes typically vary from approximately 0.014 to 0.026 (inches diameter). Examples include 0.026′′ for a commercial cook- ing appliance pilot (1,835 Btu/hr at 4′′ pressure), and 0.018′′ for a natural gas water heater pilot (879 Btu/hr at 4′′ pressure).
What happens if you run propane through a natural gas orifice?
Running propane through an orifice designed for natural gas and lower pressure will result in an overly large flame and soot. The flame will be bigger and may cause damage and even an explosion. This is because the orifice jet designed for natural gas is larger than the one for propane.
What is Orifice?
In gas grill applications, the orifice controls the flow of gas, which can be either natural gas or LP gas (propane), depending on the application.
What Does Orifice Size Mean?
The operating pressure of your machine is determined by the size of the aperture of the nozzle. As a general rule, the smaller the orifice, the greater the water flow restriction through the machine.
Functions of Orifice
The size of the orifice hole dictates the BTU (British Thermal Unit) rating of the grill as well as the kind of gas it uses. Your grill burner’s BTU rating will decide how much heat it produces. Unlike liquids and solids, gaseous substances can’t be mixed.
Importance of Using Orifice Meters in Natural Gas
The main purpose of using an orifice meter in natural gas is to measure the volumetric flow of the natural gas. But that’s not all we’ve listed the most common advantages below:
Do You Need a Natural Gas Orifice for Your Application?
An orifice is required for the operation of a gas grill. The size of the orifice hole dictates the BTU rating of the grill as well as the kind of gas it uses.
Conclusion
It seems that orifice sizes can be used for a wide variety of applications. Choose a size that gives you complete control over your work.
