A rubber profile is a door gasket made of rubber or EPDM, instead of the common PVC. Due to these material properties, it is often used in cold rooms, freezer rooms, and walk-in coolers. Rubber profiles are available per meter or on a roll. For some rubber profiles, corner pieces are also available; these have -H in the product name.
Rubber cannot be welded. For door gaskets that you order per meter, you therefore glue the corners yourself to the corner piece with rubber glue. For some profiles, we can also vulcanize the corners: the corners are assembled in the factory, allowing you to order a ready-to-use door gasket for these profiles that fits directly. Vulcanization is a time-consuming and specialized technique and therefore not possible for every profile. Whether vulcanization is available for your profile and what minimum order quantity applies, you can see in the calculation tool.
Need help finding the right rubber profile?
Not sure which profile you need? Search by brand and model of your refrigeration unit or compare the profile code with your existing door gasket. Once you have found the correct profile, you can use the configurator to specify both the color and dimensions to calculate the price directly.
How does a rubber profile work?
A rubber profile with a flap is installed in the same way as a flat profile. If the profile has a push-in arrow, the installation method is similar to a push-in profile. Some profiles must be fastened with a mounting strip. Rubber cannot be welded, so always repair or replace loose meters with rubber glue.
There are different ways to make a nice corner connection. You, as the installer, determine which method is best suited.
View the instruction videos for all different fastening methods for rubber profiles here.
When replacing, always check the old profile code or the exact dimensions, so that the new profile has the same fit and seal. If necessary, use the page dimensions of door gaskets for this.
Where is a rubber profile used?
Rubber profiles are primarily used in cold rooms, freezer rooms, and walk-in coolers. Rubber and EPDM are wear-resistant and suitable for low temperatures. This makes this material extremely suitable for heavier applications.
Find the right rubber profile
DSU supplies rubber profiles in a wide range of sizes, per meter or on a roll. For a part of the assortment, matching corner pieces are also available (-H). You can search by brand and model of your equipment to find the correct profile. If the correct profile is not listed, also check the silicone profiles category. This is because it includes profiles that are similar in shape to rubber profiles.
How to compare the right profile
The most important factor for choosing the right rubber profile or a suitable alternative is the working height and width. The working height is the part that is not under the plate/mounting strip. If the working height deviates too much, the door will not close properly. There will be a gap or the door will not close.
In the drawings on the website and in the catalog, the left side is always the outside of the profile once it is incorporated into the door gasket.
Frequently asked questions about rubber profiles
Rubber profiles can be recognized by the material: rubber or EPDM instead of PVC. If it is a large door, such as in a walk-in cold room, walk-in freezer room, or a sliding door, then it is likely rubber. The clearest difference is in the wall thickness of the profile: rubber profiles (and silicone profiles) are significantly thicker and relatively large or bulky compared to PVC and TPE profiles. Rubber profiles are supplied per meter or on a roll and are available with a flap (installation similar to a flat profile) or with a push-in (installation similar to a push-in profile). Corners are almost always glued, not welded (fused).
For some rubber profiles, suitable corner pieces are available, recognizable by -H in the product name. These are used to neatly and airtight finish the corners of the seal. If no corner piece is available, you can make the corner yourself. We provide some examples of corner connections in this video. As an installer, you decide which one fits best.
Rubber cannot be welded. Use rubber glue for this to bond profiles.
Then look for a suitable alternative profile with the same working height and width. View the explanation on Search for alternative profile. In doubt? Feel free to contact us, and together we will find the right solution.
If it can be custom-made, measure the outer dimensions or from impression to impression. If it cannot be custom-made, order the number of meters of the circumference. Good to know: we only supply full meters. If you need 5.5 meters, go for 6. Also order the corner pieces right away for the best result. You can easily glue these with rubber glue.
Yes. Because the door seal is pressed into the groove instead of being screwed or glued, replacement can be done without tools in most cases.
At DSU, we have over 900 brands; unfortunately, there is a multitude of type numbers, and new models are constantly entering the market. When the type numbers are known, they are listed on the brand page. If the type number is not known to us, that is not a problem. We produce everything to measure. Determine the correct profile and size and use the configuration tool to create the order. Optionally, add the brand and type number to the reference so that we can further complete our information.
