Rubber grommets are used in a number of applications. Grommets are available in rubber, plastic, and metal. However, there are key differences in them that can impact which one is needed for your application. To help you understand them, here is what you need to know about grommets.

What Is a Grommet?

Grommets are rings that are used for everything from signs to shower curtains. The grommets are inserted into holes in fabric as a way of reinforcing the hole and preventing a split or tear. For instance, the eyelets in your shoes through which shoelaces are woven are considered to be grommets.

Grommets are available in metal, plastic, and rubber. Rubber is one of the more popular options for manufacturing.

Which Grommet Is Right for You?

Each type of grommet has its own advantages. One of the factors to consider when selecting a grommet is determining which material type to use.

For instance, a rubber grommet is typically used when it is important to avoid the sharp edges that can occur with a metal grommet. Rubber grommets also offer flexibility that you cannot get with a metal grommet, and they are highly heat resistant. If you are using the grommet on machinery that tends to overheat, the rubber grommet is best.

A plastic grommet also is an effective alternative to metal when sharp edges are a concern. In addition to this, a plastic grommet can help prevent contamination from water or dirt when used in wiring or cabling.

A metal grommet is considered to be a highly durable option. How durable it is depends on the type of metal selected. The grommets also have a low chaff risk. As a result, ropes or cables that are passed through the grommet are less likely to experience cutting.

The application for which you need the grommet also dictates which type you select. Grommets are available in plain, spur, and drapery. Plain grommets are typically used to help in hanging flags, banners, curtains, and other fabric types.

By contrast, spur grommets are usually used in high-stress application or when there will be a lot of stress placed on the point where the grommet is placed. Drapery grommets are generally seen as decorative and are good when style is a consideration, such as in a curtain.

Before selecting a grommet, consult with a pro to get help further determining which is the right one for you.
