High-performance suction cups, C series

High-performance suction cups, C series

Standard suction cups adapt to all types of applications in branches of industry such as packaging, plastics, food, sheet metal etc. These suction cups meet a wide range of technical specifications thanks to a diverse choice of shapes, diameters and materials. COVAL offers a full range of fittings adapted to the suction cups, compatible for all types of applications.


The COVAL C series high-performance suction cup range has been designed to meet the requirements of the automotive industry. The improved characteristics of the C series range optimize production tools in all spheres of activity.

  • A full range of shapes and diameters to meet every requirement.
  • Non-slip cleats ensure optimum positioning on oily sheet metal.
  • Structured suction cups for gripping thin sheet metal without deforming the piece.
  • Ideal for automated applications.
  • Specifically for use in the stamping and welding sectors.
  • Main advantages
  • Extreme resistance to slipping.
  • Gripping thin sheet metal without deforming the piece, thanks to the central cleats.
  • Elastomer and glass-fibre reinforced plastic design to avoid any risk of damaging costly equipment and to facilitate recycling.
  • Double tightening: 2 wrenches of 22mm and 1 hex key of 6mm or 8mm.
  • Airtight fittings using:
    – O-rings on 3/8G male cylindrical suction cups 32 square suction cups.
    – Sealing on all oblong 3/8 male suction cups.



The COVAL C series vacuum cups are made out of elastomer and fibreglass reinforced plastic.
These materials guarantee long life expectancy to COVAL’s C series suction cups, high resistance to oils and heat resistance up to 100°C.

This approach helps to avoid any risk of deterioration of expensive production equipment and facilitates the recycling of suction cups.

  • Suction cups: NBR nitrile 55 Shore A (high resistance to oils).
  • Fitting: Polyamide PA 6.6 ensuring reduced weight (3/8G Male or Female fitting).
  • O-ring: NBR Nitrile blue or black.
  • Square coupling: Aluminium
