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?
Air Fren 02.1601L identifies the diaphragm fitted inside a Type 20 long stroke service brake chamber. Type 20 refers to the effective area of the diaphragm — 20 square inches — which is what determines the output force the chamber produces at a given air pressure. The long stroke designation refers to the travel available: extended-travel chambers with a deeper diaphragm profile. 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?
02.1601L is Air Fren'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 1505272, by Haldex as 025040809 and by Langendorf as 1132210.
