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.
 

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.
 

Duramax4

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

Nitrile / TPV / TPV

For general-purpose, normal ambient temperature applications. Some cups are Nitrile / TPV while others are TPV. If this specificfation is important for your application, contact us and we can let you know which material each cup is made of.
 

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.

2Continuous service temperature. Intermittent service temperature may possibly be higher. Determine via testing under actual conditions.
3Weight of Nitrile / TPV cup without fitting is tabulated. Use the ratio multiplier for other materials.
4The terms "non-staining" and "non-marking" refer only to the cup material. Airborne aerosols that attach to the cup surface or direct cup contact with dirty surfaces can result in residue transfer marks. Proper maintenance is important. Use only soap and water to wipe cups clean after installation and periodically afterward to remove airborne contaminants.
5EDCO products are made with synthetic, rubber-like materials. As such, EDCO products do not contain latex.
6All figures for shear load are 18 inHg using a 0.5 coefficient of friction. Adjust coefficient of friction to suit your conditions then apply a generous factor of safety (3:1 or greater) to shear loads.
