Most grommets are made from rubber, but plastic grommets are available in the UK and elsewhere, along with models made from other materials, including: TPV: This is a type of TPE and also called TPE-V. Its characteristics are more similar to EPDM, making it an excellent choice for sealing applications. It’s especially popular with the automotive industry for under-the-hood applications – for example, as a radiator rubber grommet – and where heat resistance and the ability to perform in oily environments is necessary. No need for oval cable to enter the box if a grommet is used. If the cable is installed when the conduit and box are installed, all should line up reasonably well and it's fairly likely you will be able to draw a replacement cable in (assuming there are not too many cables, and there are no dodgy joins in the conduit). Proper Cleaning: Depending on the material, some grommets may need periodic cleaning to maintain their protective qualities.

This table gives a high-level overview, but there’s much more to learn about each type of grommet, its specific applications, and variations within each category. If you’re selecting grommets for a specific purpose, you should consult with manufacturers or experts to ensure you’re choosing the best option for your needs. Before we look at types, we should talk about materials, which can dictate what the grommet should be used for. Known inside the industry as Blind Cable Grommets or simply Closed Grommets, these products are manufactured using a durable yet high quality TPE / PVC Rubber. Helping to provide flexibility and manoeuvrability, these materials are required for a secure fitting to your panel or cable hole, providing a quality air-tight seal which is expected of such a product.Community Discussions: Engage with other users and industry experts to gain insights and share experiences. Expert Consultations: Engage with professionals on Linquip to get insights on what kind of grommet customization might benefit your specific application. Preventing the need for adhesives or fixings, these Blind Grommets simply push fit, holding themselves in place thanks to the properties of the rubber used to create them. Blind / Closed Grommets are commonplace inside many industries, especially the Electronics industry where they are used on a daily basis to thread cables and encompass wires, greatly prolonging their life as wellas ensuring that they adhereto all health and safety requirements. Blind/Blanking grommets are the same as round grommets however they do not have a hole in the middle. They are often used to fill holes that are not currently in use to prevent dust from getting in. Some blanking grommets have a small holes in them. These are referred to as diaphragm grommets. The hole sits snug around the wire to protect it from the surrounding area and to prevent dust from passing through to the electrics behind it. Some feature a small hole into which a wire can be inserted for a firm hold. These are called diaphragm grommets. Open Rubber Grommets

Every one of our Grommets adheres to all Electrical Guidelines & Building Regulations being flame retardant. Grommets, small yet vital components in various industries, come in diverse types based on materials and applications. The key types include Rubber, Metal, Plastic, Blind, Open, Oval, Self-sealing, Collapsible, Vibration Damping, Snap-in, and Heat-resistant grommets. Their uses range from protecting cables and preventing tears to withstanding high temperatures. Linquip provides a comprehensive platform offering details, expert insights, and customization options for these grommets, reinforcing their significance in enhancing industrial efficiency. Protective Measures: Rubber grommets are used to seal off spaces, ensuring moisture, dust, or pests don’t infiltrate spaces. Round/Oval Grommets fit inside of holes that are cut into panels. They are often used to protect cables from sharp cut edges or to provide strain relief for the cable. When a hole is cut into a panel, it can often leave a sharp edge. The grommet not only makes it look better but also acts as a bumper for cables and wire that pass through. Most round/oval grommets fit by pushing or snapping into place. Usage: Used in situations where speed and ease of assembly are crucial, such as in mass production setups.Grommet strips are strips of material that sit over the edge of a panel. They are designed to improve the appearance or to protect the edge. Grommet strips are available in various lengths which are often able to be cut to size. There are heat-activated adhesive strips available too. Square rubber grommets and rectangular rubber grommets tend to feature on office furniture, such as computer desks. Here again, round grommets are common for furniture applications. For example, round rubber grommets for glass table tops are common. Finally, D-shaped rubber grommets are mostly used in machinery, computers and as automotive spare parts. How to measure rubber grommet size EPDM: The next-generation of ethylene-propylene rubber. It provides excellent electrical insulation and resists weathering, which makes it ideal for sealing purposes. It’s also why this synthetic rubber is an outstanding material for grommets. Open rubber grommets are the most basic design, featuring a central hole. They are used to protect cables and pipes when they pass through holes in metal plating. Closed Rubber Grommets
