Rubber plug assortment
We offer one of the largest rubber plug assortment you can find on the market. We as a manufacturer are proud that our rubber plug assortment is so huge and diverse. This includes a huge number of sizes, shapes, materials, colors and many other characteristics of rubber plugs that you can find in our offer. Since we know on how many different places rubber plugs are needed, we know that it is not enough to produce just a few different types from a few different materials, but that the offer must be very diverse. And that we also have to offer you the option to customize the rubber plug you order from us to perfectly match your needs.
Our offer consists of dozens of different sizes, more precisely we have pre-made rubber plugs of these sizes in our range. This also includes different shapes, because plugs, although they generally have a similar shape, when you analyze in more detail, you realize that their shape varies and that it is necessary against the holes where you will install the plugs. If you measure the hole and the plugs and realize that it differs in diameter, length or thickness or maybe all three, you can order from us rubber plugs made exclusively for you.
In our assortment you will find many different rubber materials. We will mention only some of the most popular, such as natural rubber, silicone, neoprene and FKM. The temperature range for which natural rubber is suitable is much lower than the temperature range of silicone. For example, natural rubber begins to melt at 80 degrees Celsius, while silicone can withstand 300 degrees Celsius. On the other hand, if oil resistance is important to you, then Buna-N is the right choice. All in all, we can respond to your every request.
