The best propane-to-natural-gas conversion kit is one specifically made for your grill or griddle model. For Blackstone griddles, the Blackstone 5249 is a focused option; a bundled Blackstone kit adds accessories. Weber owners can compare two kits that list broad Genesis and Spirit compatibility, then verify the exact model before buying. One product in this list converts in the opposite direction—from natural gas to propane—and is included only to clarify that it is not suitable for this search.
| Product | Best suited for | Direction |
|---|---|---|
| Blackstone 5249 | Compatible Blackstone griddles | Propane to natural gas |
| JNWYXIE Weber kit | Listed Weber grill families | Propane to natural gas |
| BBQHKCX 5249 kit | Compatible 28- and 36-inch Blackstone griddles | Propane to natural gas |
| 10-foot Weber kit | Listed Weber Genesis and Spirit models | Propane to natural gas |
| BlueStars Weber kit | Weber owners switching to propane | Natural gas to propane |
Blackstone 5249 Conversion Kit
Best for: Owners of compatible Blackstone outdoor cooking griddles who want a kit centered on the required conversion components. It includes a 10-foot, 3/8-inch natural-gas hose, a 3/8-inch quick-connect fitting, natural-gas orifices, two thread-check gauges, and a 7 mm orifice wrench.
The listed components make this a straightforward option for buyers who do not need extra grill accessories. The product information identifies brass construction and says it is made in the USA.
Limitation: The supplied details do not list specific Blackstone model numbers. Confirm the griddle’s compatibility and connection requirements before ordering.
JNWYXIE Weber Natural Gas Conversion Kit
Best for: Weber owners whose grill model appears in the product’s compatibility list. The listing names multiple Genesis, Genesis II, Spirit, Spirit II, and Summit models, including several numbered series.
This is a more complete package than a hose-only purchase. Its listed contents include a 10-foot, 1/2-inch natural-gas hose, regulator, quick connect, six sizes of brass orifices, four sizes of conversion tools, gas-rated Teflon tape, and an instruction manual. Choose it if you need the listed tools and parts together.
Limitation: Compatibility is model-specific; a grill family name alone does not confirm fit. Check the exact model against the full listing before purchase.
BBQHKCX Blackstone 5249 Kit
Best for: Owners of listed Blackstone 28-inch or 36-inch griddles, tailgaters, and rangetop combos with standard or Omnivore tops. The listing says it is not compatible with model 1902 or 17-inch and 22-inch griddles, so check size and model carefully.
The package includes a 10-foot hose with 3/8-inch inner diameter, quick connect, orifice wrench, two thread-check tools, gas-rated tape, instructions, and 16 natural-gas orifices. It also includes a reusable silicone tool mat and grease-cup liner. The listing states a maximum output of up to 45,000 BTU and describes the hose as CSA-certified.
Limitation: Its stated fit excludes several Blackstone sizes and one named model. Do not assume it fits every Blackstone appliance.
10-Foot Weber Natural Gas Conversion Kit
Best for: Owners of listed Weber Genesis, Genesis II, Spirit, or Spirit II grills seeking a kit with a 10-foot hose. The compatibility details include many Genesis model series and selected Spirit models.
The listing describes a 1/2-inch natural-gas hose, regulator, and orifice. It also says the hose uses rubber and brass, is CSA-certified, and is intended to connect appliances to an existing low-pressure supply. Choose this option if its stated model coverage matches your grill and the hose length suits your setup.
Limitation: The provided details do not enumerate every included tool or accessory. Verify package contents and exact model compatibility before ordering.
BlueStars Weber Propane Conversion Kit
Not for propane-to-natural-gas conversion: This kit runs in the opposite direction. It is intended to convert compatible Weber grills from natural gas to propane, so it is not a suitable choice for buyers changing a propane grill to natural gas.
The listed package includes a 5-foot propane regulator hose, fittings, 14 LP orifices, and two instruction manuals. The listing names several Weber Genesis and Spirit models, excludes portable Weber Q and Traveler grills, and describes the hose assembly as CSA C-US certified.
Why it is listed: Its direction is easy to confuse when searching for a conversion kit. Check the fuel direction on any kit before purchase.
Buying Guide: How To Choose A Propane-To-Natural-Gas Kit
Does the kit match your exact grill or griddle?
Start with the appliance’s full model number, not just its brand or product family. Compare that number with the kit’s compatibility list. The Blackstone options differ in how specifically they describe fit, while the Weber listings name long model ranges. If your model is not clearly listed, ask the manufacturer or seller to confirm before buying.
What parts and hose length do you need?
Compare the hose diameter and length, quick-connect fitting, orifices, regulator, and tools included. A longer hose can help with placement, but fittings and appliance requirements still need to match. Do not assume that two kits with similar product names have identical components.
Is the fuel direction correct?
Look for wording that explicitly says propane or LP to natural gas. Natural gas-to-propane kits use different components and are not interchangeable. The BlueStars item above is an example of a reverse-direction product.
What should you check before installation?
Confirm the appliance instructions permit conversion and identify any required orifice or regulator changes. Use the kit’s instructions and applicable local requirements. If the conversion steps or gas connections are unclear, use a qualified professional rather than improvising.
Frequently Asked Questions
Can I use any natural-gas conversion kit on my grill?
No. The kit must match the grill’s model, fuel direction, and connection requirements.
Can I convert a propane grill without changing its orifices?
Do not assume so. Conversion kits may include natural-gas orifices, and the appliance instructions determine the required parts and procedure.
Is a natural-gas-to-propane kit the same thing?
No. It converts in the opposite direction and is not suitable for changing a propane appliance to natural gas.
Why check the hose size and connection?
Hose diameter and fittings vary between kits. Confirm they match the appliance and the existing gas supply before purchase.
What if my model is not listed?
Do not rely on a broad brand name alone. Confirm compatibility with the manufacturer or seller before installing a conversion kit.
