About FKM Grommet

The Rubber Grommet is a connecting strap or ring which is installed into a specific hollow section by using a thin material which has specially developed edge to maintain proper position of the grommet. This grommet consists of a liner that can be easily inserted into the hole and an adjustable cap for the ease of cable access into the hole.

This rubber item is useful for protecting piercer product against abrasion or tear. It also prevents insulated cable, wire or lines that are passed through the penetrated object against abrasion. What is more, the grommet also comes in handy for safeguarding sharp edges of pierced object.

A high strength material like rubber is used for the fabrication of the grommet. The special modling design of this product helps to maintain its proper position to absorb vibration generated from machinery. It is generally placed between tripod and microphone or between chassis and radio for maintaining mechanical floating condition between two objects for inhibiting microphonism.

It is very common that the hole found in metal object or in any hard surface has sharp edges. These sharp edges can cut or damage rope, electrical wires, any soft material or cord which is inserted into the hole. Chances are that the electric insulation wire passed through this hole can break at its end point. It is, therefore, suggested to use plastic coated metal, rubber or plastic grommet to avert this damage. These types of grommets come in handy for shielding cable or wiring against contamination caused by water, dirt and air. The uniform and soft inner design of grommet safeguards wire against external damages.

Rubber Grommet is utilized where electrical wires go through drilled sheet metal or punched sheet metal or plastic casing to avoid possibility of damage. Edge grommets that are commonly referred as continuous and molded grommets are developed in different length and size options especially for this purpose. These types of grommets are available in single piece design that can be inserted manually to reduce spreading of vibration. These are extensively used for easy mounting of computer disk drives that are prone to vibration or for machinery sensitive to vibratory effect. The screws of these equipments that goes through grommet absorbs sounds produced from the chassis. Grommet is truly useful for sound insulation of electronic circuit parts that are prone to microphonism occurred due to vibration. Its presence can be noticed in data transferring cabinets, bushes with good acoustic properties, dense and complex cable or wire, telecom switches, medical devices, automobiles and in hydraulic tube used in aircraft designing.

Exceptional Material Performance

Engineered from top-quality FKM (fluoroelastomer/Viton), this grommet ensures high resistance to fuels, oils, acids, bases, and a variety of hydrocarbons. Its self-extinguishing construction meets UL94-V0 standards, and the grommet maintains superior integrity in harsh conditions, providing excellent electrical insulation and low water absorption for enhanced safety and longevity.

Customizable for Your Needs

Available in a variety of inner and outer diameters, thicknesses, and widths, the FKM Grommet can be tailored to fit varied application requirements. Clients can request custom sizes, colors, packaging, and styles, guaranteeing a precise fit whether for industrial machinery, automotive components, or sensitive electrical installations.

Effortless Installation and Maintenance

Install the FKM Grommet seamlessly with its push-fit designno special tools required. Its durable, single-piece molded construction ensures reliable sealing without frequent replacement, supporting operating pressures suitable for vacuum and pressure conditions. Bulk and custom packing options simplify logistics for manufacturers and end-users alike.

FAQs of FKM Grommet:

Q: How is the FKM Grommet installed, and are special tools required?

A: The FKM Grommet features a push-fit design, making installation simple and efficient without the need for specialized tools. This approach allows for quick, secure placement into holes or openings in various equipment and panels.

Q: What advantages does FKM material offer over natural rubber?

A: FKM, or fluoroelastomer (Viton), provides far superior chemical, oil, heat, and weather resistance compared to natural rubber. It maintains flexibility and durability in harsh chemical and temperature conditions, making it ideal for applications with demanding environmental requirements.

Q: In which industries and applications can this grommet be used?

A: The FKM Grommet is widely utilized in automotive, chemical processing, electrical/electronics, and industrial equipment for sealing and protecting apertures, especially where high resistance to chemicals, oils, and elevated temperatures is essential.

Q: What customization options are available for the FKM Grommet?

A: Clients can specify custom dimensions (diameter, thickness, width), packaging, colors, and styles (round/circular), ensuring compatibility with unique installation and operational needs. Bulk packaging and special color choices are offered per request.

Q: How long can the FKM Grommet be expected to last in standard operating conditions?

A: When installed in typical environments, the FKM Grommet offers long-term durability, with a service life often exceeding 10 years due to its robust chemical, weather, and tear resistance properties.

Q: What is the benefit of the grommets excellent electrical insulation?

A: Outstanding electrical insulation ensures safe operation in electronic or electrical applications by reducing the risk of short circuits, leakage, or other electrical hazards associated with exposed wiring or components.

Q: What is the certified flame resistance level of this product?

A: The FKM Grommet is self-extinguishing and rated UL94-V0 for flame resistance, which means it provides reliable protection in environments where fire safety is necessary.
