MAS Calibrated Mixing Pump Set
These calibrated pump sets interchangeably fit MAS Epoxies and are sold in pairs.
The 2:1 ratio makes working with epoxy as simple as counting your pumps - one pump to one pump.
These 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.
