No — a gas fitter is not the same as a plumber, but the two trades overlap on one system: the gas lines.
Plumbers' BLS job description already includes gas piping, and in some jurisdictions gas fitting is a licence of its own.
Who may install gas piping is decided state by state, so this guide compares the two trades, the licensing, and what the pay data can and cannot tell you.
Gas fitter vs plumber: the short answer
No — but the overlap runs right through the gas lines.
In the BLS occupation data the two are literally listed together: the combined occupation, 47-2152, counts Gas Plumber and Industrial Gas Fitter among its example titles, alongside Plumber, Master Plumber, Pipe Fitter, Steamfitter, and Sprinkler Fitter.
Gas work sits inside the pipe-trade family, not outside it.
The working difference is specialism.
BLS describes plumbers as installing and repairing water, gas, and other piping systems in homes, businesses, and factories — fixtures such as bathtubs and toilets and appliances such as dishwashers and water heaters included.
A gas fitter concentrates on the fuel-gas slice of that: the piping and appliances that burn natural gas or propane.
| Plumber | Gas fitter | |
|---|---|---|
| BLS job description | Water, gas, and other piping systems; fixtures and appliances | Gas Plumber and Industrial Gas Fitter are named titles in the same occupation |
| Focus | Water piping and fixtures — plus gas piping where permitted | Fuel-gas piping and gas-fired appliances, natural gas and propane |
| Who may run gas lines | Set state by state — standalone gas-fitter credentials in 14 jurisdictions; in New York City, gas piping is plumbing work under a Master Plumber with a DOB Gas Work Qualification | |
Each side has its own deep dive: our plumber career guide and our gas fitter career guide.
The rest of this page is the bridge between them.
What gas fitters install
Gas fitters install and work on fuel-gas piping — the piping systems that carry natural gas or propane to the gas-fired equipment that burns it.
The safety baseline for that piping is NFPA 54 (ANSI Z223.1, the National Fuel Gas Code), which sets minimum safety requirements for the design and installation of fuel-gas piping systems in homes and other buildings.
NFPA lists 2027 as the current edition; the edition your state enforces may differ — check with the adopting authority.
The job splits into two sides.
On the building side, the work is the fuel-gas piping NFPA 54 covers in homes and other buildings, and the gas-fired equipment it feeds.
On the utility side, the work is the gas distribution system itself, where federal pipeline rules (49 CFR Part 192, Subpart N) require pipeline operators to qualify the individuals who perform covered tasks on a pipeline facility — and a person who is not qualified may perform a covered task only if directed and observed by someone who is.
The utility side is its own career track; see our guide to utility gas fitter and gas distribution jobs.
Propane can add a second layer: separate LP-gas credentials or regulators were found in Texas (Railroad Commission), Arkansas (LP Gas Board), Alabama (LP Gas Board), Maryland (Propane Gas Fitter), Massachusetts (LP installer), Vermont (LP Gas Installer), Maine (propane technician), and Virginia (LP gas fitter).
Can plumbers do gas work?
In the BLS job description, gas piping is already plumber work: BLS describes plumbers as installing and repairing water, gas, and other piping systems.
But the permission to do that work is a licensing question, and states answer it differently.
In New York City, gas piping is plumbing work: it is performed under a Master Plumber who holds a DOB Gas Work Qualification.
In other places the state issues a gas credential separate from the plumbing licence — standalone gas-fitter credentials exist in 14 jurisdictions, and in five of the states we researched (New Hampshire, Utah, Vermont, Maine, and Massachusetts), even HVAC techs who work on gas-fired equipment need a separate state gas credential.
Texas splits the question again: LP-gas (propane) work is regulated by the Railroad Commission — not TDLR or TSBPE — and each individual must pass an RRC exam for the activity they perform and work for an RRC-licensed company.
So the honest answer is: the same job can be plumbing work in one jurisdiction — New York City requires it to be done under a Master Plumber with a DOB Gas Work Qualification — and a separate gas-fitter credential elsewhere.
Which one covers a given job is a state call, sometimes a city call.

Gas fitter licensing by state
Gas-fitter licensing is decided state by state.
Standalone state gas-fitter credentials — separate from the plumber licence — were found in Alabama, Alaska (Plumber Gas), Arkansas, DC, Louisiana, Maine (propane & natural gas technician), Maryland, Massachusetts, New Hampshire (fuel gas fitter), New Mexico, North Carolina (fuel piping), Utah (natural gas technician), Vermont, and Virginia; Texas regulates LP-gas through the Railroad Commission instead.
The requirements are concrete.
Louisiana licenses natural gas fitters separately through SPBLA: a Natural Gas Fitter needs 3,000 hours (indentured) or 4,000 hours (unindentured) of gas-fitting work and passes an 80-question exam on the 2021 International Fuel Gas Code plus a 30-minute practical; a Master Natural Gas Fitter may employ apprentices and fitters.
For the state-by-state detail — the credential names and the boards that issue them — see our gas fitter license guide.
If you are coming at this from the plumbing side, the plumbing license requirements guide explains the licence ladder a gas credential would sit beside.
Pay and demand
Start with the honest limit: BLS counts Gas Plumber and Industrial Gas Fitter as example titles inside its combined occupation, 47-2152, and publishes no separate wage or outlook for plumbers only, pipefitters only, or sprinkler fitters only.
Our research found no gas-fitter-only BLS figure.
What BLS does publish is the combined occupation, measured by the Occupational Employment and Wage Statistics (OEWS) survey for May 2025, released May 15, 2026.
The median wage was $30.67 an hour, or $63,800 a year — half earned more, half less.
BLS projects 6.8 percent employment growth from 2025 to 2035 for the occupation, above the 3.5 percent all-occupation average, with about 42,000 openings a year.
The survey excludes overtime pay, shift differentials, and nonproduction bonuses, so workers who log overtime can out-earn the published figures.
For the state-by-state numbers, see the gas fitter salary and plumber salary pages — both report the same combined-occupation data behind the role you search.
This page is career information, not legal or licensing advice. Gas-work licensing is set by state boards, LP-gas regulators, and local jurisdictions, and it changes — confirm anything you rely on with the board that issues it.
