West System 301, pump 5: 1

Intended for simple and correct dosing of West System 105 Base in combination with 205 or 206 Hardener. Mini pumps provide accurate dosing of base / hardener and reduce the risk of spillage. The pumps are screwed directly onto the base and hardener ash and are calibrated to provide five parts by weight of base to one part by weight of hardener with one pump stroke from each pump. The pumps can remain on the containers if the base and hardener are used continuously. Use 301A Mini Pumps for A-Pack, 301B Mini Pumps for B-Pack or 301C for C-Pack. A full pump stroke with each pump gives about 25 g. Base and about 5 g. Hardener. Warning: Never use with 207 or 209 Hardeners.
