Vacuum cups, also known as suction cups, can be used with workpieces that vary greatly in size, weight, surface, shape, and strength. Because of this, we have a variety of cup styles, sizes, and materials.
 
Available Vacuum Cup Styles:
  • Bellows Vacuum Cups
  • Double-Bellows Vacuum Cups
  • Multi-Bellows Vacuum Cups
  • Bellows Flat Vacuum Cups
  • Flat Vacuum
  • Flat-Concave Vacuum Cups
  • Oval Vacuum Cups
  • Universal Vacuum Cups
  • Egg Vacuum Cups

Elastomer Selection

If the cup will be exposed to oils or chemicals, select the most compatible rubber material.

Ameriflex

For general-purpose, normal ambient temperature applications. Ameriflex is a good replacement for competition PVC vinyl cups.
 

Duramax

Softer, non-staining, non-marking, general-purpose material for high-visibility surfaces at normal ambient temperatures.
 

Nitrile

For general-purpose, normal ambient temperature applications.
 

Silicone

For either cold or high ambient temperature applications where great flexibility will improve conformance to a part.
 

Conductive Silicone

For grounding parts such as electronic chips to eliminate static electricity.
 

Viton1

For extremely high-temperature applications such as automotive, appliance, or other applications where silicone is not allowed.
