The kits below are mainly designed to change compatible Weber propane grills to natural gas, while one option converts natural gas to propane.

Our Picks: Best Gas Conversion Kit For Grill reviews
1. JNWYXIE Complete Kit for a Wide Range of Weber Grills
This kit is designed to convert compatible Weber propane grills to natural gas. Its listed fit includes several Genesis, Genesis II, Spirit, Spirit II, and Summit models. The package description lists a 10-foot hose, natural gas regulator, quick connect, six sizes of brass orifices, four sizes of conversion tools, gas-rated tape, and instructions.
The range of included orifice sizes and tools may help cover different listed grill configurations, but it also makes model verification important. Don’t assume that a grill fits just because its series name appears in the description: match the full model number and confirm conversion is permitted by the grill manufacturer. The product listing does not establish that this kit is approved for every grill in those series.
Compared with the other propane-to-natural-gas options here, this kit has a similar broad accessory list to the FJXBYWM option. The Garsoo kit specifies spare orifices and a CSA-certified hose, while the MIV kit has a simpler listed component set. This JNWYXIE kit may suit you if the listed parts and model range align with your grill.
Pros:
- Includes a 10-foot hose, regulator, and quick connect.
- Provides six orifice sizes and four tool sizes.
- Lists compatibility across several Weber grill families.
- Includes instructions and gas-rated tape.
Cons:
- Fit must be confirmed against the exact grill model.
- The listing does not state a hose certification.
Verdict: Consider this kit if you have a compatible Weber model and want a broad set of conversion parts, but verify fit and manufacturer guidance before purchasing.
2. Garsoo Kit with Spare Orifices and a Certified Hose
The Garsoo kit is another propane-to-natural-gas option for listed Weber Genesis, Genesis II, Spirit, and Spirit II grills. Its parts list includes a regulator, quick coupler, adapters, tools, tape, and brass orifices. The listing describes the hose as CSA certified and says the kit includes 16 orifices plus four spares.
The spare orifices are a useful distinction if you want replacement pieces included, though having more parts does not guarantee compatibility or make a conversion suitable for every grill. The listing gives the hose as 10 or 15 feet, so check the selected configuration and make sure its length and connections work for your setup.
Compared with the other kits, Garsoo provides the clearest stated hose certification and the largest stated orifice count. Its broad model list is helpful as a starting point, but you should still confirm the exact grill model and have the installation and leak testing handled according to the grill maker’s instructions and local requirements.
Pros:
- Listing identifies the hose as CSA certified.
- Includes spare orifices.
- Lists a regulator, coupler, adapters, and tools.
- Includes an instruction manual and a stated one-year warranty.
Cons:
- Hose length varies by configuration, so check the selected option.
- A long compatibility list still requires exact model verification.
Verdict: This is a strong option to compare if the stated hose certification and spare orifices matter to you, provided your grill model and selected hose configuration match.
3. FJXBYWM Complete Kit for Genesis, Spirit, and Summit
FJXBYWM’s kit is intended for converting compatible Weber propane grills to natural gas. Its stated package includes a 10-foot, half-inch hose, regulator, quick connect, six sizes of brass orifices, four sizes of conversion tools, gas-rated tape, and an instruction manual. The compatibility list covers selected Genesis, Genesis II, Spirit, Spirit II, and Summit grills.
The parts list is similar to the first JNWYXIE kit, so the best choice between them may come down to exact model fit, current listing details, and the instructions provided. The product description says the regulator is intended to maintain steady pressure, but the listing alone cannot confirm how the kit will perform with your particular grill or gas supply.
This option is worth considering when your grill appears on its compatibility list and you prefer a kit that includes both multiple orifice sizes and several conversion tools. As with any aftermarket gas conversion, don’t treat a broad model list as proof of approval; check the grill manual or contact the manufacturer before proceeding.
Pros:
- Includes a 10-foot hose and regulator.
- Provides six orifice sizes and four tool sizes.
- Lists compatibility with several Weber grill families.
- Includes a quick connect, tape, and instructions.
Cons:
- Does not state a hose certification in the supplied description.
- Its parts list is similar to other options, so model fit is the key differentiator.
Verdict: Choose this kit only if its listed parts and compatibility details match your grill and the manufacturer allows the conversion.
4. MIV 10-Foot Kit with a More Focused Parts List
MIV’s kit converts compatible Weber propane grills to natural gas and is listed for selected Genesis, Genesis II, Spirit, and Spirit II models. The supplied description specifies a 10-foot size, a natural gas regulator, and five orifices. It is a more focused parts list than kits that include several tool sizes and extra orifices.
A shorter component list can be easier to compare, but the description does not detail every fitting or accessory in the package. Before ordering, check the current product listing to confirm what is included and compare those parts with the connection requirements for your grill and natural gas supply.
Compared with the Garsoo option, MIV does not state a hose certification or include a stated spare-orifice set in the supplied information. It may still be a suitable match if your model is listed and its included components meet your needs. Confirm the conversion is allowed by the grill manufacturer rather than relying on series names alone.
Pros:
- Specifies a 10-foot hose size.
- Includes a natural gas regulator.
- Lists compatibility with selected Genesis and Spirit models.
- Provides five orifices for the conversion.
Cons:
- The supplied description gives fewer package details than some competing kits.
- Does not state hose certification or list spare orifices.
Verdict: MIV is a reasonable kit to compare if your exact model is listed and you confirm the package includes the connections and parts your grill requires.
5. JNWYXIE Kit for Converting Natural Gas Back to Propane
This kit converts in the opposite direction from the first four: it is designed to change a compatible natural gas grill to propane. The listing describes a 90-degree propane regulator, a five-foot propane hose, 26 hand-drilled orifices in six sizes, two types of fittings, wrenches, sealing tape, and instructions.
That direction matters. If your grill currently runs on propane and you want to connect it to a natural gas line, this is not the kit to choose. Its listed fit includes selected Weber Genesis and Spirit models, but you should confirm the exact model and check the grill maker’s guidance before buying.
Among the five options, this is the only one intended for natural gas-to-propane conversion. The larger set of listed orifices may be useful for matching a compatible grill, but the number of parts does not remove the need for a correct model match and safe installation.
Pros:
- Serves the reverse conversion direction from the other four kits.
- Includes a propane regulator and five-foot hose.
- Lists 26 orifices in six sizes.
- Includes fittings, wrenches, tape, and instructions.
Cons:
- Not suitable for converting a propane grill to natural gas.
- Compatibility is limited to the models listed by the seller.
Verdict: Consider this kit only if you need to convert a listed natural gas Weber grill to propane and have confirmed that the conversion is permitted.
How to Choose a Gas Conversion Kit for Your Grill
Confirm the Conversion Direction
Start by identifying the fuel your grill uses now and the fuel you want to use. The first four kits in this guide are described as propane-to-natural-gas kits. The fifth is for natural-gas-to-propane conversion. Choosing the wrong direction can leave you with a kit that does not fit your needs, even if the grill name appears in the listing.
Match the Full Grill Model Number
Use the model number on your grill’s identification label, not just its brand or series name. Product descriptions may list many models, but versions within a series can differ. Compare the full model number with the kit details, and contact the seller or grill manufacturer if the match is unclear.
Check Whether Conversion Is Allowed
Before buying, read your grill manual or contact the manufacturer to confirm whether your specific grill can be converted. An aftermarket kit’s compatibility claim does not by itself confirm manufacturer approval or compliance with local rules. If conversion is not allowed, don’t proceed with the kit.
Compare the Hose and Connections
Check the hose length, fitting types, and connection requirements against your grill and gas supply. The options here include different listed hose lengths and fittings. A hose that is too short or connectors that do not match can make a kit unsuitable. The Garsoo listing identifies its hose as CSA certified; the supplied descriptions for the other propane-to-natural-gas kits do not state a hose certification.
Look at the Regulator and Orifice Package
These kits list regulators and orifices as key parts, but the number and sizes vary. More orifices or tools do not automatically mean better fit. What matters is whether the parts are specified for your exact grill configuration. Check the package contents and instructions before you buy, and don’t substitute parts based on appearance alone.
Plan for Safe Installation and Leak Testing
Gas work can create fire, explosion, or carbon monoxide hazards if done incorrectly. Follow the grill manufacturer’s requirements and local codes, and consider using a qualified gas appliance technician. The Garsoo listing specifically calls for a leak test after installation; any required testing should be done using appropriate methods and instructions. Never use a grill that has a gas leak or does not operate as intended.
Frequently Asked Questions
Can I convert any propane grill to natural gas?
No. Conversion depends on the exact grill model and the manufacturer’s instructions. Confirm that your grill is approved for conversion before buying an aftermarket kit.
Are these kits universal?
No. The kits list compatibility with particular Weber grill models and series. Match your grill’s full model number to the product details, and ask the manufacturer or seller if you are unsure.
Which kit converts propane to natural gas?
The first four options in this guide are described as propane-to-natural-gas kits. Their included parts and stated compatibility differ, so compare the exact model fit, hose details, and package contents.
Which kit converts natural gas to propane?
The JNWYXIE kit listed fifth is described as a natural-gas-to-propane conversion kit. It is not the right direction if you want to connect a propane grill to natural gas.
Can I install a grill conversion kit myself?
Gas installation can be hazardous and may be subject to local rules. Follow the grill maker’s instructions and consider hiring a qualified gas appliance technician. Do not use the grill unless the installation has been checked and it operates safely.
Do I need to check the hose length before ordering?
Yes. The kits list different hose lengths, and the Garsoo option may be offered in more than one length. Confirm the selected configuration and make sure it suits your grill and connection location.
What should I do if my grill model is not listed?
Don’t assume the kit will fit. Contact the grill manufacturer or seller with your full model number and ask whether that exact grill can use the kit. If you cannot confirm compatibility, choose a manufacturer-approved option or do not convert the grill.
Final Recommendation
For a compatible Weber propane grill that you want to convert to natural gas, the Garsoo kit stands out in this comparison for its stated CSA-certified hose and included spare orifices. The JNWYXIE and FJXBYWM kits also list broad Weber compatibility and include multiple orifice sizes and tools. If you need the reverse conversion, consider the fifth kit instead. In every case, verify the exact model, confirm conversion is allowed, and prioritize safe installation over a broad fit claim.
