WEST SYSTEM 1.2ltr Pump Set

West System brand pumps mount directly onto resin and hardener containers and are calibrated to dispense the correct ratio of resin hardener with a single full stroke of each pump. For those using epoxy on a regular basis, there is no better way, simply remove the original bottle cap and screw in the pump. Hang onto to cap, though the pump now seals the bottle, with it ready to dispense the right amount of resin or hardener without the need for messy setup, or tilting the bottle pouring it to the right ratio. Simply plunge the pump the right amount of times, and you're done.
Instructions:

Pumps can be transferred to new packs as needed.
Resin pump can be cleaned with two parts methylated spirits to one part white vinegar.
Hardener pump can be cleaned with water (dry thoroughly).
Periodically check mix ratio.
