303 mini special mixing pump - Yellow - 25kg - West System

Designed to be used with West System 207 and 209 Hardeners for special applications. The mini - pumps attach directly to the resin and hardener containers and have been calibrated to deliver the correct ratio of three parts resin, by weight, to one part hardener (3:1), by weight, with one stroke of each pump. One full stroke of each pump will yield approximately 25 grams of resin and approximately 8.5 grams of hardener.Warning: Do not use with 205 or 206 hardeners.
