WEST SYSTEM 301b Pump Set 5:1 6kg
West System 301B Pump Pack: Designed for comfortable and precise dosing of West System 105 resin and 205/206 hardeners. A full compression of each pump will give you the correct 5: 1 ratio required. Before using make sure both pumps are properly primed to avoid disproportionate mixing. These are the appropriate pumps for the West System B 6Kg pack.
