Rubber blanking plug
A rubber blanking plug is a small unit utilized mostly in the automotive industry to seal cavities and provide protection against sharp edges that could damage the rest of the equipment. They are ideal for closing openings and they are the best solution when it comes to overcoming issues like rusting. The units can be easily installed in pretty much every device, and they just need to be pushed inside the cavity. There are also other ways to install them, and it all depends on the type of rubber blanking plug that you have purchased, but no matter which one you choose, you will not have to use any special tools or devices to help you with the plugging. These small units provide water and dust-proof solution for all industries and they will ensure that there won’t be any debris or moisture penetrating inside the device. When installing them there are two main things that you need to pay attention to – the size of the rubber blanking plug, ergo, the opening, and the way that you install them.
We can offer you a lot of different sizes of these units, and you need to choose the dimensions depending on the opening that you want to seal. If the seal is too tight, the unit may get damaged or break, and if it is too loose, you risk debris and moisture from penetrating inside your equipment. If you need any assistance with the dimensions, you can reach out to us and we will provide the aid you need. When it comes to the installation process, you have to make sure that both the cavity and the rubber blanking plug are completely clean and dry so that you can create a tight seal that will not come loose because of moisture or dust particles. The rubber blanking plug comes in different colors, and if you cannot find what you are looking for, we can also create custom sizes or hues for your project.
