I need to assemble some weather pack connectors and some relaays and i need a quality crimping tool, i'm just not sure which i need to buy

thanks

 

Not sure if you mean Weatherpac or Packard 56 type open barrell connectors. I use an Ideal brand crimper with interchangable dies. (the one with the blue handles. It does both with the same die. I buy Packard 56 connectors (the male ones spread apart to lock into the housing) from my Interstate Battery distributor, but also get them from Waytek.com who carry the smaller guage male type 56, and also Bosck relay females and weatherpac, too.
