Round cords and round cord rings from the Dichtomatik brand achieve their sealing effect from the deformation of the cross section after installation and compression into the installation space. As static seals, they are superbly suited for tube fittings and cap seals in container construction. Round cords and round cord rings are available in the materials NBR, FKM, EPDM and VMQ. Round cords mostly serve as the base product for round cord rings. They are extruded as finite strands. A round cord ring is comparable to an O-Ring, not just in its cross-section but in its handling and application as well. Round cord rings are often used for repairs and assembled to size on site. Depending on the purpose, a round cord joint for a round cord ring can be established with cyanoacrylate (e. g. Loctite 406®) – or two-component adhesives. The temperature limit during use is about 80°C. For EPDM, VMQ and FKM round cords, a special primer (e. g. Loctite 770®) can be used in certain circumstances.
Strengths
•Media pressure strengthens the sealing function in the operational state
Round cords can be individually joined into round cord rings in the desired dimensions at the point of use
In the case of round cord rings: a high degree of flexibility thanks to customized dimensions
The material VMQ 60 is suited to food contact
