Customer Review: “This kit is GREAT! I have a Weber 2018 Weber Genesis E-325S. I read a lot of people saying the orifices don’t fit right, etc. The kit came with 3 different sizes of orifices and I was able to find the right size. All I had to get from Lowe’s was a 1/2 inch nipple to connect the quick connect to my gas line on the house. I adjusted the air (opened them up all the way) and got a good blue flame on all four burners. No more propane tanks for me. I am VERY pleased and happy that this kit worked on my grill.”

Customer Reviews
Customer Review: “Good, quality product. However, a few things to be aware of:I had go reverse the direction of the orffice in the valve. I almost missed it, as I assumed it would be properly set.You’ll need a couple of large pipe wrenches to get the cap off of the gas line.Several sets of orffices for the burners are included with the kit. Make certain you choose the correct set.Be prepared to spend a few hours completing the project. I cleaned the grill inside before starting, I had a little difficulty getting the burners off and some of the fittings were difficult to loosen, but when I was finished everything worked perfectly. No more tanks to lug around or run out during grilling. I’m very pleased with the kit I used and the end result.”
Customer Review: “Used this to adapt an Erayak tri-fuel generator to natural gas. You get everything needed and then some–a quick connect adapter which connects to a 1/2″ steel pipe for your natural gas connection, a hose which connects to it, and a regulator, which connects to the generator. Natural gas is definitely the way to go for economy and convenience.”

Customer Reviews
Customer Review: “I bought the Blue Rhino Razer LP on sale saving quite a bit compared to BlackStone. The only problem is accessories tend to be for the BS. I switched from LP to Natural Gas over the winter and thought it would be great if I could somehow run this griddle on NG. I read reviews on this conversion kit but didn’t see any Rhino conversion but I took a chance. IT WORKED!!! It took all of 40 minutes to do the conversion, fired up the Rhino and did he charge. The Griddle got hotter and got there faster. The only thing I added was RectorSeal #5 instead of the tape provided. The quality of the parts looked fine but only time will tell. At this point I would Highly recommend this conversion kit for all my Rhino compadres.”

Customer Reviews
Customer Review: “I installed this in a Costco S-435 LP and did the conversion. It was pretty simple as I did it as I assembled it. I have been using this heavily for the past month, and it seems to work great – with the 4 burners on max, I can get the grill to 500-600 degrees. If I add the sear burner, it goes past 800. I’ve tested this with pizza steels, and the grill gets hot enough to make very good pizza, which I think is the only reason I need to get to these temperatures. This kit is great because they even give you extra nozzles – which cover the main burners as well as the side burner.”
Customer Review: “The instructions are weak, and the wrench that comes with the set doesn’t fit the Weber Orifice. The wrench is 7mm, and the orifices in the Weber are 3/32. It’s not advised to use tape on the tiny orifices, it is, however, easier to use paste on them however, everything you need to do the job is in the kit!”

Customer Review: “Using the oven’s serial #, Make & Model info made easy to order the correct part needed.”
Customer Review: “Product works well. The included instructions are helpful, especially for converting the oven part to propane from natural gas. The only issue I ran into was that the included 13mm wrench was unusable because the depth of the socket was too shallow to fit the oven orifice. I had to go to my toolbox and get a deep 13mm socket to install it. Sadly the company wasted money on a tool that is unusable. Hopefully they will make a correction. Would be five stars if the wrench was usable.”
Complete Buying Guide for Natural Gas To Propane Conversion Kit
Essential Factors We Consider
When evaluating natural gas to propane conversion kits, several key factors determine suitability and performance. First, always verify compatibility with your specific appliance model—whether it’s a deep fryer, grill, stove, or oven. Next, check whether the kit includes safety certifications like CSA or UL, which ensure compliance with North American gas safety standards. Material quality matters too: brass nozzles and fittings resist corrosion far better than plastic alternatives. Finally, consider whether the kit provides all necessary components, such as hoses, regulators, or orifices, or if you’ll need to purchase extras separately.
Budget Planning
Conversion kits vary significantly in price, typically ranging from $20 to over $100 depending on complexity and included accessories. While OEM kits from brands like FRYMASTER or Henny Penny may cost more upfront, they offer guaranteed compatibility and durability. Generic or third-party kits can save money but may lack certifications or require additional parts. Factor in potential labor costs if hiring a technician for installation. For DIYers, investing in a slightly pricier kit with clear instructions and full components pays off in reduced frustration and rework.
Final Thoughts
Switching from natural gas to propane isn’t just about convenience—it can also enhance safety, reduce fuel costs, and increase appliance longevity. The right conversion kit ensures a smooth transition without compromising performance. Whether you’re outfitting a commercial kitchen or upgrading your backyard grill, prioritize quality, compatibility, and safety above all. Always follow local codes and consider professional help if unsure about gas line modifications.
Frequently Asked Questions
Q: Can I convert my deep fryer from natural gas to propane myself?
A: Yes, many conversion kits are designed for DIY installation and include step-by-step instructions. However, always turn off the gas supply and consult your appliance manual first. If you’re uncomfortable working with gas lines, hire a licensed plumber or HVAC technician to assist.
Q: Are all conversion kits universal for any deep fryer brand?
A: No, conversion kits are usually model-specific. Brands like FRYMASTER, Henny Penny, and PITCO have unique burner configurations, so you must match the kit to your exact fryer model number for proper fit and function.
Q: Do I need a permit to install a natural gas to propane conversion kit?
A: In most residential cases, minor appliance conversions don’t require permits, but local regulations vary. When connecting to a main gas line or making structural changes, always check with your city or county building department before proceeding.
Q: How do I know which nozzle size to use when converting?
A: Kits with digitally coded brass nozzles (like those from Frigidaire or Weber) make selection easy. Match the number on the nozzle to the marking on your burner—usually printed near the gas inlet. When in doubt, refer to the included conversion chart or contact the manufacturer.
Q: Is it cheaper to run propane or natural gas on a deep fryer?
A: Generally, natural gas is less expensive per BTU than propane, especially when connected to a municipal supply. However, propane offers portability and consistent pressure regardless of location. For fixed installations, natural gas usually wins on long-term cost savings.
In conclusion, selecting the best natural gas to propane conversion kit for deep fryer depends on your appliance type, budget, and installation preferences. Whether you prioritize OEM authenticity, affordability, or full accessory bundles, our top 10 list offers reliable options backed by real user experiences.
