The main purpose of u-shaped rubber grommets is to protect wires and cables from damage. Oftentimes, it doesn’t matter how carefully you handle these because they are prone to regular wear and tear caused by other objects or factors. In addition, this item needs to keep cables securely in place. This is especially important when it comes to those scattered around your home, for example, in your study or kitchen. 

This is possible not only due to the features of u-shaped rubber grommets and their design but also because of the material. As you know, they are made of rubber, which is very adjustable. Now, when ordering these, you should think about the place you want to install them. Why? Well, the best way to ensure their long life is to choose ones according to the material properties. What are we talking about? Yes, all of these are made of rubber, but not all of them have the exact same features. For example, natural rubber can sustain temperature up to 80°C, while FKM’s limit is 300°C (170°F and 572°F respectively).

Since your main goal is to invest in something durable that you won’t have to replace frequently, this is a significant thing to consider. If you need to organize wire somewhere inside your home, you don’t have to worry about external factors too much. On the other hand, if you need to use them on your porch or somewhere outside, you have to think about this. Obviously, if the latter is the case, u-shaped rubber grommets will be exposed to environmental factors such as the wind, snow, sun, heat, and so on. In addition, if you need to put them in your garage or shed, where they will be in contact with oil and similar substance, the Buna-N ones should be your choice. Yes, these are very durable, as are other rubber items, but you should still take some time to find the right ones.
