Grommets

RUBBER GROMMETS are used for the protection of a cover hole, a wire, tube, or various other objects from abrasion when they are passed through metal, plastic, or any material that could damage the outside surface of the item while being installed, or when in use. Additional applications include electrical insulation, noise reduction, vibration isolation, and protection from forces generated in compression. There are different types of grommets for a variety of applications.

What are rubber grommets used for?

Primary objective of using a rubber grommet is protecting wires, tubes, or objects from abrasion when passing through materials like metal or plastic. They also offer electrical insulation, noise reduction, vibration isolation, and protection against compression forces. 

What materials are available for rubber grommets?

We manufacture grommets using an extensive selection of rubber grades, including Silicone, EPDM, TPR, NBR, Neoprene, SBR, and Natural Rubber.

Which dimensions and specifications are important when ordering grommets?

Key dimensions include inside diameter, outside diameter, thickness (working height), groove thickness, and groove depth. These should be aligned to your specific application requirements.

What performance characteristics make these grommets ideal for industrial use?

The grommets offer excellent weather resistance, high tolerance to extreme temperatures, exceptional durability, strong chemical resistance, a secure grip, and easy installation. This makes them suitable for heavy-duty applications in automotive, wire & cable protection, and industrial machinery sectors. 

How do clients choose the right material grade for their industry application?

We provide a Material Selection Guide with ratings for temperature tolerance and performance.
