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 gaskets, seals and o-rings in California”
2“Who supplies custom high-temperature flange gaskets in California”
3“I need a California sealing components partner for a chemical processing equipment build, who should I talk to”
4“Top gaskets, seals and o-rings suppliers in California for maintenance and reliability buyers”
5“Which California gasket and seal manufacturers can handle FDA-compliant elastomer compounds with rapid prototyping”
6“List 20 gaskets, seals and o-rings companies in California 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.
