Blackstone 5249 Propane to Natural Gas Conversion Kit

The Blackstone 5249 kit is designed to convert Blackstone 28″ and 36″ griddles, tailgaters, rangetop combos, and single-burner rec stoves from propane to natural gas. Included components consist of a 10 ft 3/8” natural gas hose, 3/8” quick-connect fitting, natural gas orifices, two thread check gauges, and a 7 mm orifice wrench. The package emphasizes a straightforward setup with step-by-step instructions to ensure a safe and reliable conversion. This kit targets outdoor cooking setups where a natural gas line is available, aiming to provide consistent gas flow and heat delivery for long grilling sessions.
Compatibility and build quality are the primary considerations here. The kit’s components are standard for low-to-mid pressure natural gas applications, and the 10 ft hose length supports flexible grill placement. Users should verify their griddle’s model compatibility and follow all safety guidelines during installation to avoid gas leaks or improper venting. The kit’s emphasis on ready-to-use natural gas shafts and orifices helps maintain a steady flame, reducing propane dependency during outdoor cooking.
10FT Propane To Natural Gas Conversion Kit For Weber And More

This 10-foot conversion kit is designed to adapt LPG grills to natural gas sources, with wide compatibility across Weber Genesis, Genesis II, Spirit, and Spirit II families, including multiple model designations. The kit includes a 1/2″ natural gas hose with a regulator, plus 14 orifices in three sizes to tailor BTU output and flame stability to a wide range of Weber models. The set also includes fittings and tools necessary for installation, crafted to ensure consistent heat delivery and reliable performance after conversion. The product emphasizes safety features and a durable hose constructed from upgraded rubber and brass to withstand weather exposure and aging.
Performance considerations include ensuring regulatory compliance (CSA certification noted in some variants) and confirming the grill model compatibility before purchase. The multiple orifice sizes enable precise flame control, helping users avoid under- or over-supplying gas. For serious grillers who frequently cook at varied temperatures, this kit provides a flexible path between propane and natural gas configurations while preserving grilling efficiency.
Hosile 5369 Propane To Natural Gas Conversion Kit

Hosile’s 5369 kit provides a complete 12-foot 3/8″ ID natural gas hose with a 5/8″ OD male quick-connect plug, a 5/8″ ID female flare quick-connect, and 16 natural gas orifices. It includes multiple coupling adapters, a 7 mm orifice wrench, and thread gauges to simplify installation for Weber, Char-Broil, Blackstone, and other major outdoor grills and patio appliances. This kit is marketed toward a broad audience, from Weber Genesis to Blackstone griddles, offering a broad compatibility umbrella that supports varied modular configurations. The package notes a strong focus on safety, with robust brass fittings and a rubber core designed to withstand weathering and aging.
When evaluating this option, consider the specific hose and connector sizes your appliance requires. The comprehensive set of adapters reduces the need for additional purchases, but users should verify the compatibility notes for their exact model. The mixture of orifices and gauges supports a customizable gas flow, which can improve consistency across cooking sessions and help maintain stable temperatures during high-heat searing or low-and-slow cooking.
Sekvira Weber Natural Gas Conversion Kit

Sekvira’s conversion kit targets Weber Genesis and Genesis II lines, along with Spirit II 310/315/210 models. The package includes a 5-foot propane regulator hose, 14 hand-drilled LP orifices (three sizes), two 3/8″ fittings, a wrench, and sealing tape. The key feature is a clearly coded nozzle system—brass nozzles stamped with digital codes to help users select the correct option quickly and avoid mis-matches. The kit emphasizes flame stability, with customization designed to match the BTU outputs of different Weber models, reducing flare-ups and uneven heating during grilling sessions.
From a sourcing perspective, Sekvira emphasizes a Weber-specific fit, which can simplify installation for Weber enthusiasts. The availability of multiple orifice sizes enables precise flame control, but potential buyers should confirm their grill’s exact model compatibility and the regulator’s pressure setup before installation. The kit’s brass construction and included tools aim to deliver a durable, long-lasting conversion solution for propane-to-natural gas transitions.
Yigiao 5249 5395 Natural Gas Conversion Kit for Blackstone

Yigiao offers a natural gas conversion kit designed for Blackstone 28″, 30″, and 36″ griddles, with a wind guard option for added protection during windy outdoor cooking. The kit features a 10 ft 3/8″ ID natural gas hose, a 3/8″ male flare quick disconnect, a 3/8″ female quick disconnect, and a full set of 28 natural gas orifices. The brass components and upgraded rubber construction are highlighted for durability and longevity in outdoor environments. Notably, the kit states compatibility with Blackstone models beyond Omnivore and standard griddle tops, though there are exclusions noted for certain 1902 Culinary units and smaller models.
Considerations for this option include confirming wind guard compatibility and ensuring the hose length and fitting standards align with your specific Blackstone model. The dense assortment of orifices supports BTU customization and flame stability, helping users maintain even cooking across a variety of foods, from delicate vegetables to high-heat searing. The emphasis on brass and rubber durability suggests a design built for outdoor use and weather exposure.
Buying Guide: Key Purchase Considerations
- Grill or appliance compatibility: Confirm model numbers and brand family (Weber Genesis, Blackstone griddles, etc.). Some kits are Weber-specific, while others claim universal or broad compatibility. Mis-matched fittings can create leaks or unsafe operation.
- Hose length and fittings: Consider hose length for your outdoor space and the type of quick-connects required by your grill. Quick-connect adapters simplify installation but ensure they match your equipment’s thread specifications (3/8″ vs 1/2″ vs 5/8″ threads).
- Orifice sizes and BTU alignment: The kit’s included orifices determine flame size and heat. If you grill high-BTU items, the correct orifice prevents under-heating and flame instability. Look for a kit that provides multiple sizes for fine-tuning.
- Regulator compatibility and pressure: A stable natural gas pressure is essential for consistent cooking. Verify the regulator rating and ensure it aligns with your gas supply line’s pressure.
- Durability and materials: Outdoor use demands corrosion-resistant brass fittings and durable hoses. Brass with reinforced rubber or three-layer constructions generally lasts longer in weather exposure.
- Safety features: CSA or equivalent certifications, leak-check gauges, and clear installation instructions reduce the risk of gas leaks or improper venting.
- Installation complexity: Some kits are designed for DIY installation with clear step-by-step instructions, while others may require professional assistance for gas line work. Consider your comfort level with gas fittings and seals.
- Warranty and support: Check the warranty terms and whether the seller provides support or replacement parts if an issue arises after installation.
- Wind and weather considerations: Some kits include wind guards or are optimized for outdoor environments where wind can affect flame stability.
Overall, selecting the right natural gas to propane conversion kit involves balancing model compatibility, gas flow control, durability, and safety features. For users with Weber or Blackstone equipment, choosing a kit that specifically lists those models often reduces speculation and ensures a more reliable fit. For broader setups, universal kits with multiple adapters and orifices provide flexibility but require careful configuration to match BTU needs and gas pressure.
