Round Cord Seals Switzerland – Flexible Sealing Solutions for the Highest Demands

Round cord seals are universal sealing elements known for their easy handling and high flexibility. As round cord seals made in Switzerland, they are frequently used in automation, window and door construction, and special machine engineering. Learn why they are indispensable across so many industries.

1. What Is a Round Cord Seal?

A round cord is a cylindrical elastomer profile inserted into grooves or gaps. When compressed, it creates an even surface pressure distribution, ensuring a secure seal.

2. Material Variety

• EPDM round cord Switzerland: Ideal for outdoor use (UV-, ozone-, and weather-resistant).
• NBR round cord Switzerland: Perfect for oil and fuel sealing applications.
• FKM round cord Switzerland: Excellent resistance to high temperatures and chemicals.
• Silicone round cord: Biocompatible, food-safe, and highly flexible.

3. Application Examples

• Windows & doors: Sealing against driving rain and drafts.
• Control cabinets & enclosures: Protection against dust and moisture.
• Special machinery: Flexible seals for moving components.
• Medical technology: Hygienic seals with USP approval.

4. Advantages of Round Cord Technology

• Easy installation: Simply insert – no adhesive required.
• Flexibility: Adapts to minor tolerances and irregularities.
• Service-friendly: Quick replacement without special tools.
• Cost efficiency: Large sealing area at low cost.

Expert Tips for Design and Sizing

1. Measure groove width and depth precisely.
2. Compression of 50–70% ensures optimal contact pressure.
3. Select material according to medium and temperature.
4. Prototype testing under real operating conditions.

Conclusion

Round cord seals made in Switzerland combine flexibility and reliability. Whether EPDM, NBR, or FKM – with the right design and material selection, you’ll achieve optimal sealing performance. Our experts are happy to advise you on the sizing and selection of your Swiss round cord seal.
