Blackstone Natural Gas Conversion Kits: Top Setups for Griddle Cooks

Best for: Griddle owners with existing hoses

Pros

• Main and side burner nozzles
• Includes orifice removal tool
• Backed by 12-month warranty

Cons

• No supply hose included

Best for: Cooks wanting official factory parts

Pros

• Complete 10-foot hose assembly
• Includes thread check gauges
• Dedicated 7mm wrench included

Cons

• Incompatible with air fryer griddles

The Blackstone 5249 Propane to Natural Gas kit is engineered specifically for outdoor chefs who want a complete, single-brand conversion path from liquid fuel to an uninterrupted line. Manufactured from solid brass, this six-piece package includes a 10-foot, 3/8-inch natural gas hose paired with a 3/8-inch quick-connect fitting, designated natural gas orifices, two thread check gauges, and a matching 7mm orifice wrench. Because natural gas operates at lower delivery pressures than bottled liquid propane, replacing the burner orifices with these wider-aperture jets ensures that your burners produce proper heat distribution without flame starving.

This factory package is explicitly built for a blackstone 28 and 36 griddle natural gas conversion, ensuring that the main cooking surfaces receive consistent thermal transfer across high-heat sessions. However, the listing explicitly notes that this hardware is not optimized for tabletop units like a mini blackstone griddle or 17-inch and 22-inch frames, nor will it support pizza ovens or griddle bases that integrate an air fryer. For backyard griddle owners operating standard two-burner, three-burner, or four-burner carts within ten feet of an exterior gas stub, the blackstone 5249 natural gas conversion kit delivers an all-inclusive conversion workflow.

Best for: Outdoor setups needing extended line reach

Pros

• Generous 12-foot flexible hose
• Auto-shutoff quick connect
• 16 replacement brass orifices

Cons

• Outdoor installation only

For outdoor kitchen arrangements where a standard line falls short of the patio connection, the GASPRO Natural Gas Conversion Kit provides an extended 12-foot, 3/8-inch inner diameter hose. This package includes a quick-connect fitting with an integrated auto-shutoff mechanism, sixteen solid brass natural gas orifice nozzles, two thread check gauges, and a 7mm orifice wrench. The auto-shutoff collar halts gas flow the instant the line is decoupled, adding an essential layer of convenience when moving equipment or stowing lines away between sessions.

The extensive selection of sixteen replacement orifices allows this set to service not only 28-inch and 36-inch griddles, but also multi-configuration units such as the Tailgater combo, Rangetop models, and single-burner recreational stoves with 3/8-inch female flare connections. Griddle cooks who alternate between flat-top cooking and portable outdoor burners, including a versatile blackstone camping stove, benefit from the broad inclusion of both coarse and fine thread orifices. The listing designates this setup strictly for outdoor residential installations, making it an excellent match for extended patio layouts.

Best for: Owners sourcing factory model 5395

Pros

• Direct manufacturer model number
• Substantial 3.2-pound package
• Standard factory packaging

Cons

• Minimal listing specifications provided

The Blackstone KIT Conversion Natural Gas 5395 is cataloged under manufacturer part number 5395, arriving as a boxed conversion package weighing 3.2 pounds. The product data specifies external package dimensions of 10.25 by 10.25 by 3.02 inches and references a plate mount configuration. For cooks looking specifically for genuine manufacturer components, this listing represents the dedicated 5395 model entry designed to transition outdoor cooking stations from portable tanks to permanent utility gas lines.

Because the product listing text for the blackstone kit conversion natural gas 5395 is remarkably brief, shoppers should note that detailed internal parts counts and thread configurations are not enumerated in the description. It serves griddle owners who are specifically sourcing the factory 5395 part number to keep their setup strictly within the brand catalog. When weighing which blackstone natural gas conversion kit to buy, cooks seeking exhaustive component descriptions often cross-reference this package with the fully specified 5249 kit to confirm matching hose fittings and griddle brackets.

Best for: Cooks resolving weak burner flames

Pros

• Restores clean blue flames
• 16 solid brass nozzles
• Thread check gauges included

Cons

• Does not fit air fryer models

The Propane to Natural Gas Orifice Kit by SGTBQLL is designed specifically for griddle owners who already possess a dedicated natural gas supply hose and only require precision brass jets to adapt their burner manifold. This compact hardware kit weighs under three ounces and includes sixteen solid brass nozzles: six M6x1.0-2.0mm jets, six M6x0.75-2.0mm jets for main burners, two M6x1.0-1.39mm jets, and two M6x0.75-1.39mm jets for auxiliary side burners. It also includes an orifice removal tool, two thread check gauges, and a twelve-month warranty.

This kit accommodates a wide variety of flat-top configurations, supporting 28-inch and 36-inch griddles alongside Rangetop Combos and Tailgater systems. However, the listing explicitly warns that this hardware is not compatible with the Blackstone AirFryer Griddle Combo or the 1902 Culinary 36-inch Griddle. For outdoor cooks undertaking a direct propane to natural gas conversion blackstone project with an existing home gas hookup, swapping out the brass nozzles using the included gauges eliminates fuel starvation and provides steady burner output.

Best for: Rapid jet swaps with existing lines

Pros

• 16 solid brass orifices
• Covers main and side burners
• Includes installation manual

Cons

• Gas hose sold separately

Supplied by WADEO, the Natural Gas Grill Orifices Nozzle Conversion kit is a specialized sixteen-piece brass fitting bundle tailored for converting 28-inch and 36-inch flat-top griddles to household fuel supply lines. The package features six M6x1.0mm (2.0mm aperture) orifices and six M6x0.75mm (2.0mm aperture) orifices for primary burners, complemented by four smaller 1.39mm aperture orifices split between coarse and fine thread pitches for side burners. An installation manual is provided to guide the process, with an estimated installation timeline of twenty-five to forty-five minutes.

This hardware pack is suited for hobbyists who already have a natural gas quick-connect line installed on their deck and only require the internal brass hardware to complete a blackstone orifice nozzle conversion. The listing notes that the solid brass construction resists corrosion and thread galling during removal and reinstallation. Because it omits the bulky rubber hose, this kit is remarkably compact, making it convenient to store or transport if you manage auxiliary burners or recreational stoves at secondary outdoor cooking spaces.

The Natural Gas Orifice Nozzle Conversion Kit from Otolyle addresses flame regulation issues that occur when running a factory propane manifold on low-pressure natural gas. When fuel apertures are too restrictive, griddles exhibit weak flame output and uneven heating. This sixteen-piece solid brass nozzle set supplies the wider 2.0mm main burner orifices and 1.39mm side burner orifices necessary to achieve clean blue flames and rapid griddle surface recovery. The kit includes two thread check gauges and a dedicated orifice tool for simple mechanical replacement.

Compatibility extends across standard 28-inch and 36-inch griddle frames, stovetop combos, cooltops, and single-burner recreational cooking units, though the manufacturer notes it does not fit the AirFryer Griddle Combo. Backyard griddle cooks upgrading their patio cooktop will find that this orifice set delivers the exact mechanical hardware required to re-jet burner assemblies without paying for duplicate hoses or regulator fittings they may already own.
