If you need to convert a deep fryer from natural gas to propane, the first step is to find a kit approved for your fryer’s exact make and model. The products below are not listed as deep-fryer conversion kits: they are intended for certain griddles, grills, or ranges. Some also convert in the opposite direction. Treat this list as a comparison of related gas-conversion products, not as confirmation that any one will fit your fryer.
Before buying, check your fryer’s manual or contact its manufacturer. Gas type, burner orifice size, regulator, and connection must all match the appliance. If you cannot confirm compatibility, do not install a conversion kit.

Our Picks: Best Natural Gas To Propane Conversion Kit For Deep Fryer reviews
Blackstone 5249: A Propane-to-Natural-Gas Kit for Specific Griddles
The Blackstone 5249 is a propane-to-natural-gas conversion kit for compatible Blackstone 28-inch and 36-inch griddles. It is the reverse of what someone needs when changing a natural-gas fryer to propane, so it is not a match for that job based on the supplied product details.
The kit includes a 10-foot natural-gas hose, a 3/8-inch quick-connect fitting, natural-gas orifices, thread-check gauges, an orifice wrench, and instructions. Its hose and quick-connect setup may suit someone connecting a supported griddle to a natural-gas line. The product information excludes several other appliances and griddle sizes, including 17-inch and 22-inch models, pizza ovens, and griddles with an air fryer.
Owners of compatible griddles may appreciate having the hose and conversion parts together, and some describe the changeover as straightforward when following the instructions. Still, installation reports for a griddle do not establish fryer compatibility. Do not use this kit on a deep fryer unless the fryer’s manufacturer specifically approves it.
Pros:
- Includes a 10-foot hose and quick-connect fitting.
- Includes orifices and tools for its stated griddle conversion.
- Made for specified Blackstone 28-inch and 36-inch griddles.
Cons:
- Converts propane to natural gas, not natural gas to propane.
- Not listed as compatible with deep fryers.
Verdict: Choose this only if you have a listed Blackstone griddle and want to connect it to natural gas; it is not the right direction or a confirmed fit for a natural-gas deep fryer.
Weber Grill Conversion Kit with a Propane Hose and Orifices
This kit is described as a natural-gas-to-propane conversion for certain Weber Genesis and Spirit grills. The listing says it includes a propane hose with a regulator, brass LP orifices in multiple sizes, fittings, tools, sealing tape, and instructions. Those parts are presented for the listed grill families, not for deep fryers.
The assortment of orifices may help match a conversion to different supported grill configurations, but the listing does not provide a fryer compatibility claim. Its title and description are worded broadly, so check the precise grill series and model against the kit instructions before ordering. Do not assume that parts made for a Weber grill can be adapted to a fryer.
For an owner of a compatible Weber grill who is moving from a natural-gas connection to propane, a kit that includes the hose, regulator, orifices, and tools may reduce the need to source parts separately. For a fryer conversion, the appliance manufacturer’s approved kit remains the safer route.
Pros:
- Includes a propane hose and regulator, along with conversion orifices.
- Lists compatibility with specific Weber Genesis and Spirit grill families.
- Includes tools and instructions in the package description.
Cons:
- Not listed for deep fryers or other appliance brands.
- Exact grill model fit should be confirmed before purchase.
Verdict: Consider it for a matching Weber grill after checking the model details, but not for a deep fryer without explicit approval from the fryer’s manufacturer.
Frigidaire LP Kit for Listed Gas Ranges
This kit is intended to convert certain Frigidaire or Electrolux gas ranges from natural gas to propane. The listing names specific model numbers and says the package includes brass nozzles, installation tools, a gas-type label, and instructions. That makes the model list especially important: a similar-looking range is not enough to confirm a match.
The stamped nozzle codes are meant to help identify which part goes where, while the included tools and instructions provide a more complete package than a set of loose orifices. However, this is a range kit, and the supplied information does not identify any deep fryer as a compatible appliance. Range components should not be treated as interchangeable with fryer components.
This option may be relevant if you are converting one of the exact listed ranges and have confirmed the part is suitable for your appliance. If your target is a commercial or home deep fryer, look for a kit specified for that fryer’s model and burner system instead.
Pros:
- Describes a natural-gas-to-propane conversion for specified ranges.
- Includes brass nozzles, tools, a gas-type label, and instructions.
- Lists model numbers to help shoppers check fit.
Cons:
- Designed for listed Frigidaire or Electrolux ranges, not fryers.
- Requires careful model-number matching.
Verdict: This is a possible option for an exact compatible range model, but it is not a deep-fryer conversion kit according to the supplied details.
Blackstone-Compatible Conversion Kit with Conflicting Listing Details
This third-party kit is presented as a Blackstone-compatible conversion set for certain 28-inch and 36-inch griddles, tailgaters, and rangetop combos. Its description lists a 10-foot hose, quick-connect fitting, orifices, tools, instructions, and additional accessories. It also gives exclusions, including certain smaller griddles and a specific model.
There is a key uncertainty: the product title and description do not agree clearly on the conversion direction. The title refers to a natural-gas conversion kit, while the description uses conflicting propane and natural-gas wording. Since the gas type determines which parts are needed, do not rely on the title alone. Confirm the exact direction with the seller and compare it with your appliance manual before buying.
Even if the direction is clarified, the listed compatibility is for Blackstone outdoor cooking equipment rather than deep fryers. The accessories may make it a broad griddle kit, but they do not establish fit for another appliance type.
Pros:
- Lists a hose, quick-connect fitting, orifices, and installation tools.
- Names several Blackstone griddle and outdoor cooking configurations.
- Provides exclusions that help narrow down griddle fit.
Cons:
- Listing details conflict about conversion direction.
- Not identified as compatible with deep fryers.
Verdict: Treat this as a cautious, model-specific griddle option only; do not order until the seller confirms the conversion direction and the appliance manufacturer confirms compatibility.
Another Frigidaire Range LP Kit with Marked Brass Nozzles
This kit is also described as a natural-gas-to-propane conversion kit for certain Frigidaire and Electrolux ranges. The listing names a set of model numbers and says the package contains brass nozzles, two tools, a gas label, and instructions. The nozzle markings are intended to make it easier to identify parts during an eligible range conversion.
Its stated use is similar to the other Frigidaire range kit in this list, so the deciding factor should be exact model compatibility and the manufacturer’s guidance—not the general phrase “LP conversion kit.” The supplied details do not state that this set fits a deep fryer, and they do not establish that it is interchangeable with another range kit.
For a listed range model, the included tools and labeled parts may be useful. For a fryer, choose a conversion kit documented for the fryer’s exact model, or ask the manufacturer or a qualified gas appliance technician to identify the correct parts.
Pros:
- Lists specific Frigidaire and Electrolux range models.
- Includes marked brass nozzles, tools, a gas label, and instructions.
- Describes conversion from natural gas to propane.
Cons:
- Not listed for deep fryers.
- Model compatibility must be confirmed before installation.
Verdict: This may suit a specifically listed range, but it is not a substantiated choice for converting a deep fryer.
How to Choose a Natural-Gas-to-Propane Conversion Kit for a Deep Fryer
Start with the fryer’s exact make and model
Find the fryer’s model label and check its manual for an approved conversion procedure or part number. A kit intended for a range, grill, or griddle is not automatically suitable, even if it uses the same fuel types. If the manufacturer does not list a conversion kit for your model, contact its support team before buying parts.
Confirm the conversion direction
Natural gas to propane and propane to natural gas are different conversions. The correct kit needs parts specified for the direction you are changing. Read the listing and instructions carefully, and get clarification if the title, description, or packaging uses conflicting wording. Do not guess based on a hose or fitting’s appearance.
Check that the kit is approved for your appliance
Compatibility should name your fryer’s brand and model, or be confirmed by the fryer manufacturer. Orifice size, regulator, burner design, and connection requirements can vary by appliance. A kit’s compatibility with a similar fryer—or with another kind of gas appliance—is not proof that it will work safely.
Review what the package includes
Depending on the approved kit, conversion parts may include orifices, a regulator or hose, fittings, tools, labels, and instructions. Compare the package contents with the manufacturer’s conversion requirements. A kit that appears complete for a grill or range may still lack the parts needed for your fryer.
Consider who should perform the conversion
Changing gas type is not just a matter of swapping a hose. Follow the appliance manufacturer’s instructions, and use a qualified gas appliance technician if the procedure is unclear or if the manufacturer calls for professional service. Do not operate the fryer until the conversion and gas connections have been checked as directed.
Do not treat a general-purpose listing as proof of fit
Product titles can be broad, and some descriptions may contain unclear or conflicting claims. Look for a clear statement of appliance model compatibility and conversion direction. If either is missing, contact the manufacturer or seller for confirmation before purchasing; if compatibility cannot be verified, choose another route.
Frequently Asked Questions
Is any product in this list confirmed to work with a deep fryer?
No. The supplied product details identify these kits for Blackstone griddles, Weber grills, or Frigidaire and Electrolux ranges. None is listed as a deep-fryer conversion kit.
Can I use a range conversion kit on a fryer?
Not unless the fryer’s manufacturer specifically confirms that the kit is compatible with your exact fryer model. Similar fuel types do not mean the parts are interchangeable.
How can I tell whether a kit converts natural gas to propane?
Check the product description, instructions, and compatibility information for the stated “from” and “to” fuel types. If those details conflict, ask the seller or manufacturer to confirm before buying. The Blackstone 5249, for example, is described as a propane-to-natural-gas kit, which is the opposite direction from the target conversion.
Why does the fryer’s model number matter?
Conversion parts are selected for a specific appliance configuration. The manufacturer’s model information helps confirm the correct kit and instructions, rather than relying on a general product label or a visual match.
Is a hose-only change enough to convert a fryer?
Do not assume so. A conversion may require specific parts and instructions for the fryer, not just a different hose. Follow the manufacturer’s approved procedure and use a qualified technician when needed.
What should I do if my fryer manufacturer does not offer a conversion kit?
Contact the manufacturer for guidance and ask whether conversion is permitted for your model. If they cannot confirm an approved method, do not adapt a kit made for another appliance.
Final Recommendation
None of the five products here is confirmed as the best natural-gas-to-propane conversion kit for a deep fryer. The Blackstone 5249 converts in the opposite direction and is intended for select griddles; the other options are described for particular grills or ranges, not fryers. For a safe, compatible choice, start with your fryer’s exact model and obtain a conversion kit or installation guidance approved by its manufacturer. If you cannot verify the fit and conversion direction, do not install the kit.
