Rubber Grommet Suppliers will share this article with you.

Let's start with the most basic-what is a rubber grommet? They are accessories used to cover sharp edges in electrical engineering and manufacturing. This may have some functional benefits—for example, a ring-shaped grommet helps prevent cutting and friction from damaging wires, cables, and pipes.

They also provide additional protection against dust and water. This kind of grommet is usually fixed with a horn collar. Or, the edge bands with rubber grommets may just provide a more satisfying appearance of the device where they are connected.

They are usually black, but you will also find transparent and gray variants.

There are several alternative names for rubber grommets, including:

Edging

Eyelet

Bushing or insulating bushing, used with electrical appliances (size no more than 51 mm)

Use of rubber grommets

Rubber cable grommet is a multi-purpose product that is widely used in many industries. Their main uses include:

Cover the hole tip of the metal plate to prevent the cables and pipes from being cut and scratched and prolong the service life. A common example is an electronic backbox. These are rectangular chambers embedded in the wall for placing plugs and power sockets. The entry and exit points of the wires are protected by grommets.

The rubber grommet provides strain relief, grasps the wire in place, and will damage and destroy that may occur if the wire or cable is accidentally pulled. A good example of this usage is the ethernet and other ports on the back of PCs and laptops.

Industries that routinely use rubber grommets include:

Electronic product

Construction

Automotive Engineering

Aircraft Engineering and Avionics

Telecommunications

Internet Data Center

Medical device manufacturer

Rubber is an elastic substance and has many advantages compared with other grommet materials. It resists:

Weather

Moisture

Heat

Low temperature

Ozone

Ultraviolet (UV)

Hydrochloric acid, saltpeter, phosphoric acid, and sulfuric acid

Alkali environment

Strain

The rubber is not dry, cracked, and not easy to loosen. The rubber grommet does not require a thread, so it can be inserted more easily, and it does not require a lock nut, so it can be inserted from only one side. Rubber grommets are push-fit, which means they are only secured by internal pressure and expansion, so no adhesive is required.

What are rubber grommets used for?

For this particular type of application or process, rubber grommets are usually used. Generally speaking, rubber grommets are more commonly used to protect or cover the hole, and to protect cables or wires from sharp corners or edges.

What is the function of the grommet?

A rubber grommet is an accessory of wiring equipment. There is a hole for the wire to pass through the middle. The purpose is to protect the wires from being cut by sharp plate cutting and to prevent dust and water. It is widely used in various fields such as electronics, electrical appliances, machinery, sports equipment, furniture, and lighting. There are many kinds of rubber materials used in the production of rubber grommets. Commonly used materials are nitrile rubber, natural rubber, neoprene, silicone, and fluoro rubber.
