Can the S type and L type ZH series vacuum ejectors be distinguished by appearance alone?

ZH series body ported type vacuum ejectors can be distinguished by the color of the ring part (diffuser part) in the middle of product.
The ring of the S type is brown, and the ring of the L type is black.
However, for the old type, the ring of the S type is silver and the ring of the L type is black.

In addition, there is either an “S” or an “L” molded into the diffuser part.
