About partflux

As an industrial maintenance manager, I spent way too much time trying to track down compatible replacement parts. Cross-reference data is scattered across dozens of manufacturer catalogs, each in a different format, and none of them talk to each other. I built partflux to solve that problem.

partflux is a free, open cross-reference search engine. Type in a part number and instantly see equivalent parts from other manufacturers. No accounts, no paywalls, no ads.

The data is sourced directly from manufacturer cross-reference catalogs and is continuously being expanded. Right now the database covers 835,000+ parts across 3,700 manufacturers and OEMs, with over 700,000 cross-references linking them together.

This is very much a work in progress. If you notice incorrect data or have suggestions, feel free to reach out. More brands and part types are on the way.
