300 Mini Pumps are designed for convenient and accurate metering of all Group Size A, B and C WEST SYSTEM resin and hardeners.

They mount directly on the resin and hardener containers and eliminate the mess involved with measuring by weight or volume. 300 Mini Pumps are calibrated to deliver the proper working ratio with one full pump stroke of resin for each one full pump stroke of hardener.

Pump Sets are available for each West System Pack Size (A, B or C):

West System 301 Pump Set for 5:1 mix 205 & 206 Hardeners

West System 303 Pump Set for 3:1 mix 207 & 209 Hardeners
