Transition kit to help customers with converting to 3M's new 50ml Duo-Pack cartridge design. 3M(TM) Scotch-Weld(TM) EPX Cartridge Transition Conversion Kit, for manual EPX applicators for the new 1:1, 2:1. 3M Scotch-Weld Duo-Pak Cartridges in 48.5ml and 50ml sizes. Kit includes 12 EPX square-green mixing nozzles in the new design (B-system-screw-on style), One new shared/universal EPX plunger for 50ml dispensing guns (that works with the new cartridge design) , and one 3M Orientation & Instruction Sheet. 3M has moved from a traditional bayonet cartridge to the Sulzer B-System cartridge. While this new B-System cartridge does offer a number of advantages and advancements, it also requires a different static mixer nozzle and in some cases a different cartridge extrusion plunger and/or cartridge gun. This kit was built by 3M to help/simplify the transition of customers to using the new cartridge system.
