Industrial Molded Grommets

Industrial molded grommets are small rubber components used to protect wiring and cables from fraying or being cut when passed through a pre-drilled hole. Some grommets are also designed to provide vibration control in motor and machine assembly applications.

Molded grommets perform well in indoor or outdoor applications because they can withstand a wide temperature range and retain their shape after being distorted. Additional advantages of rubber grommets include:

  • Durable
  • Flexible
  • Corrosion resistant
  • High-heat resistant
  • Weather resistant
  • Easy installation

Common Applications for Industrial Molded Grommets

While most molded grommets are circular, there are also hinge-shaped, oval-shaped, and pushbutton grommets used for sealing, protection, and vibration control. Some of the typical uses for rubber grommets include:   

  • Installing rubber molded grommets in thru-holes and machine holes to protect wires and cables from sharp metal edges.
  • Creating a dust barrier and weather-tight seal by inserting molded grommets in holed used to pass tubes, wires or cabling through walls and cabinets.  
  • Attaching rubber grommets to brackets and bolts for vibration control in applications involving motors or machinery.
