Custom Large 1mm 2mm 5mm Inlet Oval Furniture Lubricating Single Wire Seal High-Temperature Automotive Firewall Waterproof Electrical Silicone Rubber Grommets
Types of Rubber Grommets
-
Open Grommets:
- These have a hole through the center and are used to protect wires or cables as they pass through metal or other hard surfaces. They prevent abrasion and damage to the cable.
-
Blind Grommets:
- These are used to seal off holes in structures, providing a clean and neat appearance. They are ideal for applications where wires or cables do not need to pass through but the hole still needs protection or insulation.
-
Multiple Hole Grommets:
- Designed to manage several wires or cables through a single grommet, these are used in situations where space is limited but multiple cables need routing.
-
Multiple Hole Grommets: Electrical Seal Connactor:
A connector seal is used to protect multi-wire connectors or terminals. It provides a watertight and dustproof seal around the connector, ensuring the integrity of multiple connections within one assembly. Connector seals are usually larger and designed to accommodate more than one wire, whereas SWS focuses on individual wire sealing.

Sealing Grommets, commonly known as a Cable Seal Grommet, are self sealing grommets that are ideal for use in oily and greasy environments.
Materials Used in Grommets and Wire Seals:
-
Silicone:
- Properties: High flexibility, excellent heat resistance (up to 300°C), and superb electrical insulation. Silicone also resists UV light, ozone, and moisture, making it ideal for outdoor conditions.
- Applications: Primarily used in high-temperature environments like automotive engine compartments, electrical equipment near heat sources, and in applications requiring a cleanroom environment due to its low toxicity and low chemical reactivity.
-
EPDM (Ethylene Propylene Diene Monomer):
- Properties: Excellent resistance to weather, UV radiation, ozone, and aging. EPDM also has good heat stability and low electrical conductivity.
- Applications: Commonly used in automotive door seals, window seals, and in HVAC systems where prolonged exposure to water and high temperatures is common.
-
3.Nitrile Rubber (NBR):
- Properties: Offers excellent resistance to oils, solvents, and other hydrocarbons. Nitrile is known for its strength and durability.
- Applications: Used in applications where resistance to oil and chemicals is critical, such as in automotive fuel handling systems, hoses, and other oil-related applications.
-
4.Neoprene:
- Properties: Good chemical stability and flexibility over a wide temperature range. Neoprene is also flame resistant.
- Applications: Used in electrical insulation, and as vibration damping structures in automotive and marine applications due to its durability and resistance to degradation.

Customization and Design Considerations
-
Size and Thickness:
- Grommets must be precisely sized to fit the holes they will seal and thick enough to withstand the forces they will encounter without deforming.
-
Tolerance and Fit:
- Tight tolerances are crucial for ensuring that grommets provide proper sealing and fit securely in their applications. Custom tooling can be developed to meet specific design requirements.
-
Environmental Factors:
- Depending on their use environment, grommets may need to resist UV light, ozone, saltwater, petroleum products, and more. Material choice is critical to meeting these requirements.

- Grommet: A grommet is a ring or eyelet that is inserted into a hole, typically in a material like fabric, plastic, or metal, to protect wires or cables from abrasion and wear. Grommets also help to prevent fraying and can serve decorative purposes. They are often used in electrical and plumbing applications to create a clean, finished look around holes.
Specific Applications
-
Electrical Insulation:
- Rubber grommets act as an insulating barrier between wires and metal edges, preventing electrical shorts, which is crucial in automotive, aerospace, and consumer electronics.
-
Vibration Damping:
- In machinery and engines, grommets reduce the transmission of vibration, thereby protecting delicate components and reducing noise, which is vital in automotive and industrial applications.
-
Environmental Sealing:
- Specific types of rubber grommets provide environmental sealing to prevent the ingress of moisture, dust, and other contaminants, particularly useful in outdoor electrical enclosures and automotive exteriors.

Specific Applications and Environments:
-
Lubricating Single Wire Seals: These are designed to prevent the ingress of moisture and contaminants while maintaining the integrity of the wire or cable. Often used in automotive electrical systems where wire lubrication is also needed to reduce the friction of electrical cables passing through the firewall or chassis.
-
High-Temperature Automotive Firewall Waterproof Electrical Silicone Grommets: Specifically designed to protect electrical systems from extreme temperatures and environmental exposure while maintaining wire integrity in automotive firewalls.
-
Rubber Grommets in General: Serve a wide range of applications from protecting cables from sharp corners and edges, to isolating vibrations and reducing noise. They are used in various industries including automotive, aerospace, electronics, and construction.
