Rubber Grommets

Rubber grommets are attachments used in electrical engineering and manufacturing to cover sharp edges.

Functions of rubber grommets

Rubber cable grommets are versatile products that are widely used in several industries. First of all, They are applied to cover the sharp edges of holes in metal plates to protect cables and pipes from cuts and chafing damage, prolonging their useful life. A common example is an electrical backbox. These are rectangular chambers inserted into walls to house plugs and power points, with the wiring entry and exit points protected by grommets. Besides, rubber grommets provide strain relief, gripping wiring in place and minimizing the damage and disruption that might occur if the cord or cable was accidentally pulled. A good example of this usage is ethernet and other ports at the back of PCs and laptops. In addition, automotive rubber grommets can also reduce engine vibration in cars and other vehicles.

Types of rubber grommets

Rubber blanking plugs are employed for sealing apertures and are engineered to retain and regulate pressure emanating from above or below, thus rendering them an optimal grommet selection for high-pressure UK equipment and tubing. Certain models incorporate a small aperture into which a wire can be inserted for a robust fixation. These are designated as diaphragm grommets. Open rubber grommets, the simplest design, feature a central aperture. They serve to safeguard cables and pipes when they traverse holes in metal plating. Closed rubber grommets are also recognized as blind rubber grommets, which can be a viable choice for sealing unoccupied holes to avert the accumulation of dust. Unlike round grommets of similar shape, blind rubber grommets are devoid of a central aperture. A further classification is the semi-blind grommet. These incorporate a central membrane that is sufficiently thin to be penetrated by wires or cables. This implies that semi-blind grommets can serve as substitutes for both open and closed grommets.

Advantages of rubber grommets

The single most important reason to use a rubber wire grommet in every installation is that it protects against sharp edges that could do damage to your wires. Even edges that are a little sharp can wind up doing irreparable damage to critical cabling. Besides, water poses a significant threat to electrical installations of all types. A significant advantage of utilizing rubber hole grommets is their remarkable water resistance. If installers are routing cables through an environment prone to moisture, it is crucial to mitigate this issue by utilizing rubber grommets as a seal. Rubber grommets also exhibit a natural resistance to organic acids and most contemporary chemicals.
