Dimensional data is not published. Manufacturing tolerances vary between production batches, and a fixed published figure that a shipment later disagrees with is worse than no figure at all. Fitment is confirmed by Type and stroke, and by the OEM number stamped on your chamber.

What is this part?
Sem Lastik 15871 identifies the diaphragm fitted inside a Type 9 normal stroke service brake chamber. Type 9 refers to the effective area of the diaphragm — 9 square inches — which is what determines the output force the chamber produces at a given air pressure. The normal stroke designation refers to the travel available: standard-travel service brake chambers. A diaphragm of the wrong Type or the wrong stroke will either not seal correctly or will not deliver full travel, so both figures have to match.
What does this number tell you?
15871 is Sem Lastik's own catalogue reference, not a vehicle manufacturer's. Aftermarket suppliers assign their own numbers to the same part, which is why the number printed on a box rarely matches the one in the service manual.
The same diaphragm is catalogued by DAF as 1257928, by Bendix as 234433 and by BPW as 02.220.30.10.0.
