26 more companies were named at least once. Companies outside the top ten are counted in the averages but not named here.

Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Indiana. They belong to that state's ranking, not this one.

Company	State	Mentions
Ferguson Industrial	Washington	5 of 15
Industrial Service & Supply, Inc.	Texas	4 of 15
American Hose & Hydraulics	New Jersey	3 of 15
Alfa Laval / Tri‑Clover	Pennsylvania	2 of 15
Corrosion Technologies, Inc.	Ontario	2 of 15

Named, but placed in another state

The AI answers themselves put these companies in a different state, so they were not counted for Indiana. Whether MacRAE'S lists them elsewhere is not yet known.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best suppliers of pipe and tube fittings in Indiana”
2“Who supplies stainless steel sanitary tri-clamp fittings in Indiana”
3“I need a Indiana pipe and tube fittings partner for a high-pressure chemical process line installation, who should I talk to”
4“Top pipe and tube fittings suppliers in Indiana for industrial maintenance buyers”
5“Which Indiana pipe and tube fittings distributors can handle large-diameter, high-pressure alloy specifications”
6“List 20 pipe and tube fittings companies in Indiana with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
