DSLA 150 P442 nozzles. The nozzles sold by this seller are defective. I ordered several types, some of them Brazilian Bosch, others Chinese of different brands, but I got the impression that all these nozzles that I ordered were made by one manufacturer. The problem is that there is a deep chamfer around the needle, which is not on the original nozzles, this is what prevents the nozzle from working, because the second stage sleeve falls into this recess.
