Duraflex dual-durometer suction cups from Piab Vacuum Products (Hingham, MA) are made of polyurethane that combines the elasticity of rubber with the wear resistance of polyurethane.
Cups are ideally suited for applications where microleakage can occur. Cups leave no marks on the handled parts. Energy can be saved when using these new cups. Smaller vacuum pumps can be used or air-driven vacuum pumps can be run at a lower air pressure because less leakage occurs as the cups grip the product. Built-in filters protect the vacuum system from dust and dirt.
