Rubber grommets are common tools used for covering the holes and protection of cable wires from sharp edges or corners. Wires and cables connected to different devices may be damaged due to sharp ends and this damage is highly dangerous. Rubber grommets help protect the wires and holes from such damage. In this article, we will tell you about different types of rubber grommets, their uses, qualities, and where to buy online.
Rubber grommets are used for the following purposes:
- Rubber grummets don’t let the wires damage by sharp cuttings.
- They are dustproof and waterproof hence protect the cables from being affected by dust and rain.
- Rubber grommets are necessary tools in electronics, sports, furniture, equipment, lighting, and electrical appliances at homes, offices, shops, and factories.
They are made of different types of rubber and synthetic materials according to their particular purpose. Nitrile rubber, natural rubber, neoprene, silicone, and fluoro rubber are frequently used materials in grummets. They are hard with high tensile strength.
The Rubber Grommets are available in different shapes according to their particular application. For example:
- Blind hole
- Special shape
Properties of Rubber grommets according to the material:
The rubber grommets made from different kinds of rubber have different properties and uses. Let’s discuss a few of them.
- Natural rubber grommets
They are strong and tough, difficult to crack. The natural rubber has high tensile strength and tears strength with good insulation properties as well.
- Buna-N grommets
Sometimes grommets have to be in contact with oil, for this Buna-N grommets should be used as they have oil resistance. It is a semiconductor, with low volume resistance and good antistatic properties.
- Silicone grommets
Bright colored grommets are usually made of silicone. It is safe as it is not harmful to human skin. Silicone is favorable for the environment. Silicone grommets are mostly used in medical equipment.
- FKM grommets
The fluororubber grommets are highly stable in alkaline and acidic environments. Their temperature is also high that makes them stand even at 300-degree Celsius temperature.
- Neoprene grommets
Neoprene grommets are resistant to high temperatures, extreme weather conditions, and ozone aging. They are best to be used under sunlight and flame.
Types of rubber grommets:
Rubber grommets are now available in different shapes, sizes, materials, and other properties. You can choose the grummet of your choice which is most favorable for your work and the purpose of using it.
- Rubber grummets Type-A
- Oval Grummets
- Water poof grummets
- Wire grummets with the long neck
- Specially shaped grummets
