MWT (Euro5) Connector Crimping

Hi all, has anyone got a good tool to use for crimping MWT connectors (the red Euro5 can connector)? Pins are here: https://www.mouser.com/ProductDetail/JST-Automotive/SMWTWS-A021T-064?qs=u16ybLDytRYumOD43a%252BPaw%3D%3D

I was able to crimp the wire to the pin with my 3187CT, die 'E', but I can't find a good crimp for the seal. I tried an ECT47 crimp tool, but the round 'A' slot was too big, and the smaller round 'B' slot was too tight and tore the plug.

Thanks for any suggestions!
