WEST SYSTEM epoxy resin and hardeners are packaged in three "Group Sizes." For each container size of resin, there is a corresponding sized container of hardener. When purchasing resin and hardener, be sure all containers are labeled with the same Group Size letter (A, B or C). The 300 Mini Pumps can be configured to fit any Group Size.
