WEST SYSTEM 301 Pump Set 5:1

Accurate mixing is essential for achieving the full performance of any epoxy system. The WEST SYSTEM 301 Pump Set 5:1 is designed to eliminate measuring errors by automatically dispensing the correct amount of resin and hardener with every full pump stroke.

Specifically developed for WEST SYSTEM 105 Epoxy Resin combined with 205 Fast Hardener or 206 Slow Hardener, the pump set mounts directly onto the original resin and hardener containers, providing a fast, clean, and convenient dispensing solution.

Each complete stroke of the resin pump combined with one complete stroke of the hardener pump delivers the precise 5:1 mixing ratio required for optimum curing, maximum bond strength, and long-lasting durability. This significantly reduces material waste while ensuring consistent mixing for every application.

Whether you’re carrying out yacht maintenance, fiberglass repairs, wooden boat restoration, composite construction, or professional bonding applications, the WEST SYSTEM 301 Pump Set makes epoxy preparation quicker, cleaner, and far more reliable than manual measuring.

Manufactured from durable chemical-resistant materials, the pumps are designed for repeated use and are trusted worldwide by boat builders, marine professionals, composite manufacturers, and woodworking specialists.
