Switching an appliance from propane to natural gas requires parts designed for that appliance and gas type; a regulator or fitting alone may not complete the conversion. Of these five products, the adjustable regulator is the closest match for a propane-to-natural-gas setup. The grill regulator also lists natural-gas operation, while the dryer and range kits are for the reverse direction: natural gas to propane. The splitter distributes gas but does not convert an appliance. Check the appliance manual and have a qualified gas professional confirm parts and installation requirements.
| Product | Best suited for | Important distinction |
|---|---|---|
| TEENGSE adjustable regulator | Applications needing an adjustable NG/LP regulator | Lists settings for both gas types; original setting is LP |
| GRILLJOB grill regulator | Natural-gas or propane grill regulator applications | Lists 4-inch NG and 10-inch LP water-column settings |
| Yulatik 3-way valve | Controlling two gas branches | G1/2 BSPP threads, not standard 1/2-inch NPT |
| Gugaguga dryer kit | Converting a natural-gas dryer to propane | Reverse direction from propane to natural gas |
| GRLP4 range kit | Converting certain ranges to propane | Reverse direction from propane to natural gas |
TEENGSE Adjustable NG/LP Gas Regulator
Best for: Buyers whose appliance or system specifically calls for an adjustable regulator that can be set for natural gas or propane. It is the most directly relevant item here for a gas-type change because its listed specifications provide separate outlet-pressure and flow information for NG and LPG.
The product uses 1/2-inch FPT inlet and outlet threads and includes two brass adapters: a 1/2-inch NPT male to 3/8-inch flare male adapter and a 1/2-inch NPT male-to-male adapter. Joint thread tape is also included. The listing says the original setting is LP and describes changing the LP/NG shaft-core direction, with a top-screw adjustment also noted for natural-gas use.
- Listed natural-gas outlet pressure: 0.95–1.05 kPa, or 4 inches water column.
- Listed LPG outlet pressure: 2.45–2.55 kPa, or 10 inches water column.
- Maximum working inlet pressure is listed as 1/2 PSI.
Limitation: The product’s maximum inlet pressure and connection type must match the intended installation. It is not a substitute for an appliance-specific conversion kit or professional confirmation of gas pressure requirements.
GRILLJOB Natural Gas Grill Regulator
Best for: A grill application that calls for a low-pressure regulator with separate natural-gas and propane settings. The listing gives an outlet pressure of 4 inches water column for NG and 10 inches water column for LPG, so buyers can compare those specifications with the grill manufacturer’s requirements.
The regulator has 1/2-inch NPT pipe-thread inlet and outlet connections. Its listed maximum inlet pressure is 1/2 PSI, and its stated gas flow is 120,000 BTU per hour. The listing describes the outlet pressure as adjustable between the 4-inch and 10-inch water-column settings. It also states that the product passes CSA certification; buyers should verify that the item and installation meet their local requirements.
Choose this if the grill’s documentation calls for a regulator with these connection and pressure specifications. Limitation: The listing says propane use requires an external regulator, which is not supplied. Do not assume the regulator alone converts a propane grill to natural gas; burners, orifices, and appliance approval may also matter.
Yulatik Brass 3-Way Gas Valve
Best for: Buyers who need to control gas flow to two separate branches from one supply, after confirming the valve and all other parts are suitable for the specific gas system. Its two independent shut-off handles allow each outlet to be controlled separately.
This is a distribution valve, not a propane-to-natural-gas conversion device. The product is made of solid brass and is described as a G1/2 BSPP male-thread valve. The listing emphasizes that these threads are not standard 1/2-inch NPT, the thread type commonly used in many U.S. household gas connections. An appropriate adapter may be needed, but thread compatibility alone does not establish that an installation is safe or approved.
Choose this if you need two independently controlled outlets and have verified the thread standard and application. Limitation: Avoid it if you need a direct 1/2-inch NPT fitting or are looking for an appliance conversion kit. Confirm the valve’s suitability with a qualified installer before use in a gas line.
Gugaguga LPK1 Gas Dryer Conversion Kit
Best for: Owners converting a compatible natural-gas dryer to liquid propane—not for a propane-to-natural-gas conversion. This direction matters: the product description specifically says it converts a natural-gas dryer to use liquid propane.
The package contains two items and is described as replacing part numbers 649P3, LPK1, and 14218952. Its brass components are described as durable and corrosion resistant. The listing says it fits and operates in most dryer brands, but that broad wording does not confirm fit for any particular model.
Limitation: This kit is the reverse of the requested conversion direction. Do not use it to convert a propane dryer to natural gas. Check the dryer’s model-specific parts documentation before ordering, and follow the manufacturer’s instructions or use a qualified appliance technician.
GRLP4 Frigidaire Range LP Conversion Kit
Best for: Owners of certain compatible ranges, stoves, or cooktops who need to convert from natural gas to propane. The kit is not for changing an LP appliance to natural gas, so it does not match the requested direction.
The product includes 12 brass orifices and is described for sealed-burner models with prefixes including FG, FF, FP, CF, CRG, BG, CG, DG, LP, LG, LF, and WW. The listing names Frigidaire, Kenmore, and Electrolux appliances and gives replacement numbers AP5608114, 318565427, 2319698, and 5304498798. These details are useful for checking a model, but they do not guarantee compatibility with every appliance from those brands.
Limitation: This is an LP conversion kit for the opposite gas-direction change. Do not select it for a propane-to-natural-gas project. Verify the range’s exact model and required kit in its manufacturer documentation.
Buying Guide: How to Choose Propane-to-Natural-Gas Parts
Does the part match the direction of conversion?
Start by confirming which gas the appliance uses now and which gas it will use after conversion. “LP conversion” usually describes changing an appliance to liquid propane; it does not mean converting propane equipment to natural gas. In this product selection, the dryer kit and GRLP4 range kit are explicitly for natural-gas-to-propane conversions. They are not suitable choices for the reverse direction based on their descriptions.
A regulator that lists both NG and LP settings may be relevant, but it does not prove that the appliance itself can be converted. Some appliances require model-specific orifices, valves, adjustment procedures, or a manufacturer-approved kit. Check the appliance manual before buying parts.
What pressure and flow specifications should you compare?
Compare the appliance’s specified inlet pressure, required gas type, and fuel demand with the regulator’s stated limits. The TEENGSE regulator lists 4 inches water column for natural gas and 10 inches for LPG, with a maximum working inlet pressure of 1/2 PSI. The GRILLJOB regulator lists those same outlet-pressure figures and a stated flow of 120,000 BTU per hour. These figures are not interchangeable with a general assurance of compatibility.
Do not adjust a regulator based on guesswork. If the appliance documentation does not clearly identify the correct settings, ask the manufacturer or a qualified gas professional to confirm them.
Will the threads and fittings connect correctly?
Thread labels matter. NPT and BSPP/G1/2 are different thread standards, even when a product description uses a similar nominal size. The Yulatik valve explicitly warns that its G1/2 BSPP threads are not standard 1/2-inch NPT. The TEENGSE regulator lists 1/2-inch FPT ports and includes adapters, while the GRILLJOB regulator lists 1/2-inch NPT connections.
Check the thread type at every connection point, not just the pipe diameter. Do not force mismatched fittings together or assume an adapter makes a part appropriate for a particular gas application. Have a qualified installer determine whether a connection is suitable.
Is a regulator enough to convert the appliance?
Usually, a regulator should not be treated as a complete appliance conversion. A gas appliance may require components designed for the new fuel, and the correct parts depend on its make and model. A grill regulator, for example, does not by itself establish that a propane grill can safely operate on natural gas.
Use parts specified by the appliance manufacturer for the exact model and conversion direction. If the manufacturer does not list an approved conversion, do not assume that a general-purpose regulator or fitting makes the change safe.
When should a professional handle the work?
Gas conversion involves fuel pressure, leak prevention, and appliance operation. Use a qualified gas professional when the manual calls for professional installation, when you cannot confirm compatibility, or when the work involves changing a gas line or adjusting gas controls. Follow local codes and the appliance manufacturer’s instructions.
After installation, the system must be checked according to applicable instructions and requirements. Do not operate an appliance if you suspect a leak, smell gas, or cannot confirm the installation is correct. Follow the gas utility’s emergency guidance if you suspect a leak.
Frequently Asked Questions
Can I use an LP conversion kit to switch a propane appliance to natural gas?
No. An LP conversion kit generally refers to converting an appliance to liquid propane. The Gugaguga dryer kit and GRLP4 range kit in this list are described for natural-gas-to-propane conversion, the opposite direction.
Which product listed here is most relevant to a propane-to-natural-gas change?
The TEENGSE regulator is the closest match because its description includes both natural-gas and LPG settings. However, it is only appropriate if its pressure, flow, connections, and use match the appliance requirements. It is not a universal conversion kit.
Can a regulator alone convert a propane grill to natural gas?
Do not assume so. A regulator does not confirm that the grill’s other components are suitable for natural gas. Check the grill manual for an approved conversion process and required parts.
Are G1/2 BSPP and 1/2-inch NPT the same thread?
No. The Yulatik listing specifically warns that its G1/2 BSPP threads are not standard 1/2-inch NPT. Confirm thread standards before selecting fittings.
How do I know whether a conversion kit fits my appliance?
Match the kit’s part number and stated application to the appliance’s exact model number and manufacturer documentation. Brand names or a list of model prefixes alone do not confirm compatibility with every appliance.
