West System Pumpset for A-Pack 5:1

Designed for convenient and accurate dispensing of West System 105 Resin and 205/206 Hardeners. One full compression of each pump will give you the correct 5:1 ratio required. Prior to using, ensure that both pumps are properly primed to prevent off-ratio mixes. WARNING: DO NOT USE WITH 207 OR 209 HARDENERS!
