WABCO Brake Chamber Diaphragms — Cross Reference

We cross-reference 25 WABCO brake chamber diaphragm numbers across 10 sizes. Each one links to the Viaforta replacement, the equivalent numbers other manufacturers use for the same part, and the vehicles it is fitted to.

WABCO builds air brake systems rather than vehicles, so these numbers follow the chamber onto every make fitted with it. They are the references stamped on the chamber itself, which is why one number maps to several vehicle catalogues at once.
