15 Feet 3/8 in Natural Gas Conversion Kit for Blackstone Griddles

Our review of the 15 ft natural gas conversion kit explains who benefits most and why it is worth considering. This kit is aimed at Blackstone griddle owners who want a permanent, steady supply of natural gas and prefer a durable, flexible hose and solid brass fittings. The single biggest reason to buy is the complete, purpose-built package: a 15 ft 3/8 in ID hose with quick connect fittings and 16 orifices, which lets most 28 in and 36 in Blackstone griddles run on natural gas without hunting for adapters or extra parts.

Key Features

• Natural gas compatibility: Enables a consistent connection to a natural gas line so you do not need to worry about running out of propane during long cooking sessions.
• Durable hose construction: The stainless steel inner layer and natural rubber outer layer resist weathering and cracking, which helps the hose last through outdoor use.
• Solid brass fittings: 100% brass 3/8 in quick connect and flare fittings reduce the chance of leaks and make connection and removal straightforward.
• Complete orifice kit: Includes 16 natural gas orifices plus a 7mm orifice wrench so you can convert multi-burner griddles without sourcing extra parts.
• Length and reach: The 15 ft hose gives flexibility in positioning a griddle relative to the gas source, which is helpful for patios and permanent outdoor kitchens.

Who It's For

This conversion kit is best for owners of Blackstone 28 in and 36 in griddles, Tailgater, Rangetop Combo, and single burner rec stoves who want a reliable natural gas hookup and easier long-term use. It suits people who are comfortable doing a DIY conversion and appreciate having the correct orifices and fittings included.

It is not appropriate for users who need indoor-rated equipment, those with AirFryer Griddle Combo models, or anyone using the 1902 Culinary 36 in griddle that is not compatible with natural gas. If you need a shorter or non-quick-disconnect setup, look for alternate hose lengths or hard plumbing solutions.

Pros & Cons

Cons

• At least one customer reported an issue with leak resistance, so careful testing after installation is required.
