When it comes to creating connections, using the right gas fittings is imperative in the plumbing realm for a safe and secure job.
A gas fitter is a plumbing specialist who should have the knowledge needed for a job done right. They’ll also understand the different types of gas fittings and when (and where) they are best used. It’s important to keep in mind that while understanding these different fitting types can be helpful to your conversations with a plumber or gas fitter, you will want to leave the work to the professionals. In fact, it’s illegal to try to perform your own gas fitting work.

How to choose the right gas fitting comes down to two main features: size and operation.
Most gas fittings are designed to create connections between different lengths or directions of pipe or tubing, but not all tubes are created equal when it comes to size or material. Gas fittings help professionals literally fit together the different tubes to create a singular flow between the source of the natural gas and the appliance powered by it.
Operation is more than just whether or not you need a valve to operate the flow of natural gas. It’s a measure of how much pressure and temperature the fitting is designed to operate under or withstand. Different fittings come with different ratings, which a professional will reference in order to use the right type.
Types of gas fittings by connection
- Compression fittings make a connection and seal by placing pressure on a gasket, ring, or ferrule.
- Mechanical fittings leverage two ferrule grips that press into each other and create a seal.
- Bite-type fittings use ferrules that dig into the pipe and create a natural compression seal.
- Flange fittings are connected to pipes by using clamps or welding.
- Flare fittings handle high pressure by creating a seal inside the tube with a flared end.
- Threaded fittings use grooves to accept matching threads including female and male surfaces.
Types of gas fittings by material
- Cast iron
- Stainless steel
