The West System 303 Pump Kit was designed for convenient and accurate metering of West System resin and hardeners.
For convenience, the pumps mount directly onto both the larger sized Resin and Hardener containers and deliver the correct working ratio of 3 parts of 105 resin to 1 part of either 207 Special Coating or 209 Super Slow hardeners. With one full pump stroke of resin for each one full pump stroke of hardener.
- This kit is specially designed for the 4L epoxy (105) and the 1.33L Special Coat Hardener (207).
- This pump kit cannot be used on the smaller sizes (1L epoxy & 330ml hardener).
Note: If you have a 205 or 206 Hardener, the ratio is 5:1 so you would need a 5:1 pump kit (301).
Made of durable polypropylene, the pumps give years of use. Pumps may be left in containers during storage.
