Empty 50ml Adhesive Cartridge Kits for 1:1 ratio adhesives, with included Hand Plungers, 3-inch Mixing Nozzles, and Resealable Cap. Each kit includes either 5, 10, 25, 50, or 100 cartridge kits and all included hand Plungers, Mixing Nozzles, Resealable Caps, and necessary sealing pistons to close and seal the empty cartridges. Perfect for storing and applying bulk adhesives that use a 1:1 mix ratio, where precise metering and mixing is needed. NOTE: The included hand plungers work best with thin or low viscosity adhesives. In fact, using the included manual hand plunger with many thicker 2-part adhesives can be difficult to mix and push out of the cartridge. If you are using medium or thick/low viscosity adhesives, we recommend also getting one of our 50ml Dispensers, which will vastly improve the ability to dispense the adhesives out of these cartridge kits.
