Common protective tool used in mechanical, electrical, automotive, and building sectors is rubber grommets. It mostly serves to avoid wire breakage or electrical short circuits and shield objects like cables and pipelines from damage by sharp metal edges. diverse application environments translate rubber grommet into diverse kinds and materials; common ones are natural rubber, chloroprene rubber, and silicone rubber.
Rubber grommet has more benefits in temperature resistance, corrosion resistance, wear resistance and other aspects than metal and plastic grommet can keep good performance in demanding settings. As environmental protection criteria get better, more and more rubber grommet uses environmentally friendly materials and satisfies international environmental protection criteria. Rubber grommet is now a necessary protection tool used in many different fields all around.
What is a rubber grommet?
Usually put in a hole, a rubber grommet—a ring-shaped tool composed of rubber material—protects objects such cables, wire harnesses, pipes, etc. passing through the hole. Its primary purposes are to prevent wear or damage resulting from friction and impact as well as cables, pipelines, etc. from direct contact with the surface of the equipment or the metal edge of the hole. Rubber grommet can also be isolating, shielding wires from outside environmental impact and therefore lowering safety risks including leakage and electrical short circuits.
Material of rubber grommet
Usually either synthetic or natural rubber, the particular choice depends on the use environment and performance criteria of rubber grommet. Typical rubber kinds are natural rubber, chloroprene rubber, silicone rubber, etc. Suitable for general use events, natural rubber has good elasticity and wear resistance; chloroprene rubber has strong oil resistance and chemical corrosion resistance; silicone rubber has better high temperature resistance and UV resistance; Therefore, depending on different working situations, it is quite vital to choose appropriate rubber grommet materials, which can guarantee the stability and dependability of the product in long-term use.
Forms and applications for rubber grommet
There are three typical variants of rubber grommet, mostly depending on distinct application criteria: flat type, edge type and insertion type. Every kind of design finds particular use in a different field.
Usually utilised on flat surfaces, flat-type grommet rubber may efficiently isolate the friction between the wire and the surface of the equipment. Commonplaces in electronic equipment, control cabinets, etc. are it.
Often used on the edge of the device to shield the wire from cutting or abrasion by the metal edge, edge-type grommet Commonly found in cars, electrical appliances, machines, and other tools are vehicles.
The insertion-type grommet can be straightly fitted into the equipment’s hole to shield the cable or pipe. Appropriate for mechanical equipment, pipeline systems, etc., this kind of grommet is easy to install.
Many sectors and uses make advantage of these several kinds of rubber grommet. Rubber grommet is used in the electrical sector to guard power systems, shield cables from wear between equipment housings and cables, and so guarantee their safety. In the automobile sector, rubber grommet is inseparable from cable and pipeline system protection; it not only prevents wear on wires but also significantly lowers shock and extends the service life of electrical systems. Particularly in complicated electrical pipeline wiring in the building industry, rubber grommet’s protective action is notably noticeable and helps to greatly reduce friction and damage between wire pipes and walls or floors.
Characteristics of rubber grommets
Rubber grommets have clearly shown benefits in several facets when compared to cable grommets made of other materials like metal and plastic. Rubber first of all has outstanding flexibility and wear resistance. Rubber grommets are not easy to break or distort even in long-term use; they can also preserve good shape and function. Second, rubber grommets help to drastically lower the danger of damage resulting from friction by efficiently preventing direct contact between cables and metal surfaces. Rubber grommets can simultaneously guarantee equipment’s safe running, prevent short circuits or leaking of electrical equipment, and offer electrical isolation.
Furthermore, rubber itself has strong corrosion resistance; this is particularly true of rubber grommets composed of either silicone or chloroprene rubber, which can resist the erosion of oil and chemicals, thus fit for petrochemicals, chemical industry, and other sectors. Extreme temperatures make silicone rubber grommets especially remarkable; they can also withstand either high or low temperatures, therefore guaranteeing the stability of machinery in demanding surroundings.
Furthermore under more and more focus is the environmental performance of rubber grommets. Many rubber grommets are composed of environmentally safe materials, satisfy international environmental requirements, do not emit toxic compounds, and have minimal effect on the environment during use as environmental consciousness rises. This makes them increasingly often employed worldwide, particularly in ecologically friendly industry sectors.
Comparison of various materials and rubber grommets
Apart from rubber, other materials of grommets available on the market are plastic and metal grommets. Rubber grommets have more advantages and adaptation than these materials.
Comparatively to plastic grommets, their high temperature resistance, corrosion resistance, and durability are sometimes worse than those of rubber grommets even if they are low-cost and quick to install. Rubber does better in demanding conditions including high temperature and humidity.
Comparatively with metal grommets, which are typically employed in high-strength and high-pressure situations but are often hefty and readily damaged objects like wires. Conversely, rubber grommets are small in weight and simpler to install; their softness and elasticity help to considerably lower wear on wires.
Rubber grommets: little extras with great impact
Many disciplines benefit much from rubber grommets. Apart from shielding objects from friction and breakage, including cables, wires, and pipes, it also offers insulation between equipment to prevent electrical mishaps. Rubber grommets may satisfy various environments and use criteria by selecting the appropriate material and type, so safeguarding the safe and stable running of industrial equipment. Rubber grommets have shown its indispensible worth in industries such electronics and electrical, vehicles, machinery, building, or manufacturing.
