How Dispensing Tools Work

Building a Tool

There are 3 core components in a dispensing tool: The Drive, the Material Containment Unit (MCU), and Nozzle. By customizing these components to meet your specific application needs, you can create the optimal dispensing tool.

Creates initial force or thrust

Material Containment:
Holds the material in bulk, sausage or cartridge

Reduces material to desired size and shape


Mechanism that creates force or thrust. There are three drives available:

  • Manual Drive: hand operated, portable, and efficient. A wide range of drive ratios are available to match the viscosity or nozzle back pressure.
  • Air-Powered Drive: requires an air compressor, regulator, and hose. This set-up is best for industrial applications.
  • Cordless Drive: portable, powerful, fast and effortless.

Material Containment Unit (MCU)

Contains the material to be dispensed.

  • Bulk Material: Sealants and adhesive supplied in pails.
  • Sausage Packs: Packaged in a Mylar bag which fits a sausage specific tool.
  • Cartridge Material: Portable and convenient. Single and two-component.


Determines the size and shape of the material to be dispensed

Engineering Tidbit

Single Action Air Guns
  • Air power allows for smooth dispensing
  • Manual load improves speed and quality
  • Its simplicity improves reliability
  • Air pressure = material containment pressure
Dual Action Air Guns
  • Air power in both dispensing and loading directions
  • Commonly used on two component applications
  • Commonly used on single component applications
