These work very well in both of my string trimmer machines. The old ones leaked and I used these to replace them. It was easy to just disconnect the old ones and connect these and they fit and function like the original ones.Highly recommend!

The dimension you show as 19 mm is actually 21 mm. The 19mm dimension is actually the OD of the actual plastic primer bulb. The outer case dimension is 21mm. That means it fits my John Deere BH25 Leaf Blower perfectly. If I had known that at the time of purchase I would not have spent for $7 for one advertise as an exact replacement. I'll live.

Great replacement for my Troy Built leaf blower, theyare inexpensive, and good to have them available, because the original failed after some uses.
