Sampa Brake Chamber Diaphragms — Cross Reference

We cross-reference 16 Sampa brake chamber diaphragm numbers across 8 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.

These are Sampa's own catalogue references, not a vehicle manufacturer's. Aftermarket suppliers number the same part their own way, which is why the number printed on a box rarely matches the one in a service manual. The table below resolves both.
