Epoxy Pumps

These calibrated pump sets interchangeably fit MAS Epoxies & System THREE epoxy bottles.  They do not fit WEST System epoxy containers (find WEST System pumps here).

The 2:1 ratio makes working with epoxy as simple as counting your pumps - one pump to one pump.

• The smaller pumps are made by MAS and are standard in the MAS Economy Kits.  They pump in a 2:1 ratio --- 8cc of resin and 4cc of hardener.
• The larger pumps are made by System THREE.  They also pump in a 2:1 ratio --- 30cc of resin and 15cc of hardener.  Minor assembly is required.  You will need to slip a regulating collar on the hardener pump to ensure proper 2:1 metering.  Instructions are here (PDF).
