Customised seals
Customised gaskets manufactured according to drawing or sample
When it comes to customised gaskets, you place particularly high demands on your supplier or manufacturer. This is because, unlike seals in standard dimensions, such as O-rings, the requirements for seals made to drawing or sample are much more individualised. They must be precisely matched to your application and its environment in every respect and property - from the design and construction to the tolerances and material selection.
We at KREMER supply you with:
• Dichtungen aus EPDM
• FFKM-/Krevolast®-Dichtungen
• Flachdichtungen
• NBR-Dichtungen
• Profildichtungen
• Silikon-Dichtungen
• wasserstrahlgeschnittene Dichtungen
as well as customised hose rings manufactured in-house. We also process seals made from CR and FKM/FPM materials.
As a technical purchaser, designer or technician, you know from your own experience that every application, every installation situation and every operating environment places its own, sometimes very specific requirements on industrial seals. For example, seals in the food and beverage sector must have high media resistance and a wide temperature range in terms of material selection, while at the same time complying with strict hygiene regulations and the requirements of the FDA and EU1935/2004.
In systems in the fuel, hydrogen or chemical industries, on the other hand, optimally selected and designed seals ensure safe operating processes and efficient production. The risk of degradation of the sealing material due to environmental influences and thus of leaks, failures and environmental pollution is minimised. When procuring seals, it is therefore a basic requirement that your supplier fully understands and realises your specific requirements. You expect him to be able to advise you on material selection and design and to meet you on an equal technical footing. In any case, however, they should be familiar with the sealing-specific characteristics of various industries and have a wealth of experience in customised seals.
You can play it safe with KREMER: we have been supplying and advising companies from every conceivable industry for many decades. During this time, we have become very familiar with the many industry-specific intricacies - so you can always rely on your customised seals to fully meet - or even exceed - your requirements.

Customised seals: That's why KREMER
Three good reasons why you have the ideal supplier for customised seals at your side with us
If you want to have a gasket customised according to a drawing or sample, then you expect your contact person to meet you at eye level and understand your requirements in detail. If necessary, you want comprehensive and, above all, personalised advice - from the choice of the right manufacturing process to the design of the gasket and the selection of the ideal material.
You can feel that you are in good hands in all these matters, because customised seals have been our speciality for many decades - across all industries. Our team knows the intricacies of the actual product and its material properties, as well as the many processes behind the development and production of a gasket. This is why many of our customers give us positive feedback on our technical advice - for example, the fact that new approaches are often developed during the initial discussions with our product developers in order to adapt the customised seal even better to the application environment.
We are also happy to support you during the product development phase with rapid prototyping at our company. Your advantage: you will have a dimensionally accurate prototype model in your hands within a very short time, which makes it easier to further develop and optimise your seal. This enables you to get your seals or moulded parts ready for series production even more quickly and cost-effectively.
In addition to gasket expertise, the time factor is important to you when procuring customised gaskets: you need a transparent and meaningful quotation quickly. Your production and delivery processes must continue seamlessly, which is why you want to receive your seals according to drawing or sample within the shortest possible time.
The KREMER team is prepared to do just that. Thanks to our wealth of experience in the field of customised seals for industry, we are able to calculate quickly and accurately for you. As soon as you have sent us your enquiry with your specifications or discussed it personally with our specialist advisors, you will usually receive your individual quotation within 48 hours. In addition, once we have all the relevant data, we will do everything we can to keep the delivery time for your customised gaskets as short as possible.
Despite our speed, expertise in providing advice on sealing technology and economically attractive conditions, the quality of customised seals is our top priority. After all, they play an important role in your production and operating processes, where process safety in particular must be guaranteed.
It goes without saying that the high quality of customised seals is also one of our greatest strengths. On the one hand, we are certified in accordance with DIN EN ISO 9001 and DIN EN ISO 14001. On the other hand, you benefit from an enormous wealth of experience gained over almost six decades. During this time, we have worked with customers from every conceivable sector and industry, many of whom have extremely strict quality standards when it comes to customised seals.
Our criteria for selecting our suppliers are correspondingly strict. And this applies both to the quality of the materials from which your seals are manufactured and to the environmental and ethical standards you require as part of a responsible supply chain.

It all depends on the dimensions!
The KREMER calculation programmes allow you to calculate the parameters of your application quickly and precisely. Because O-rings, moulded parts or rubber profiles can only function optimally if the dimensions are correct. With just a few clicks, you can carry out installation and tolerance calculations with the KREMER calculation programmes.
The use of self-adhesive film for elastomer products can be helpful for the user for several reasons. Self-adhesive gaskets are used, for example, for overhead installation of a gasket or to prevent loss during transport of pre-assembled components.
When gaskets, especially profile gaskets with self-adhesive film, are used as an assembly aid for installation, this means that the self-adhesive film has no influence on the function of the gasket after installation.
Self-adhesive stamped gaskets on film are a convenient solution that makes installation easier and safer. If the adhesive film is to have a function other than that of a self-adhesive film for installation purposes, this must be explicitly stated in the enquiry. Our product advisors will carefully check the information on the intended use and include it in the offer according to the possibilities.
In addition to the proper processing and handling of the self-adhesive film in the seal manufacturer's production facility, the storage of the finished elastomer products at the customer's premises plays a decisive role in the durability of the self-adhesive elastomer and silicone products.
The right processing
- Ensure sufficient and even contact pressure.
- Processing tools (including hands) must be free of release agent.
- In the case of extreme loads on bonded joints, it should be noted that the maximum adhesive strength is only reached after approx. 24 hours.
- Avoid permanent tension on the bond.
Underground:
- Do not apply to surfaces containing silicones, paraffins or waxes.
- Do not use paints with adhesion-reducing additives.
- Ensure freedom from dust.
- Ensure freedom from plasticisers.
- Ensure dry surfaces.
- Cover as smooth, closed surfaces as possible.
- Exclude chemical reactions of the surfaces.
Temperatur:
- The optimum bonding temperature is between 20 and 30°C in dry rooms.
- If possible, do not work below 10°C.
- Storage temperature at 18°C and approx. 55% relative humidity.
Influences that impair the adhesive strength of the self-adhesive film:
- High humidity, grease, oil, dust and/or dirt on the surfaces of the parts to be bonded.
- Plasticiser migration.
- Improper storage (deviating from DIN 7716).
Storage and shelf life
In principle, the following applies self-adhesive Seals only a limited shelf life can be assumed. It is possible that the shelf life of the film is shorter than the warranty period of 12 months for self-adhesive products. It is therefore particularly important that the Storage and processing instructions are complied with. We recommend, the self-adhesive products within six months to process.
Warranty conditions "Self-adhesive products"
The product must be processed within six months of delivery, taking into account the above-mentioned storage temperature, humidity and processing instructions. No liability/warranty can be accepted for products processed at a later date.
