Round Cords and Round Cord Rings

Endless round cord for static applications

Round cords are manufactured by extrusion and traded by the meter. Compared to O-Rings, round cords can be used as endless round cords or with a joint as a round cord ring. However, they are subject to larger tolerances in the inner diameter (d1) as well as in the cord diameter (d2). Round cords are used for sealing larger pipe joints and cover sealing, e. g. in tank construction. They are often used for on-site repairs, where they are joined "to size". The cords can be joined together to form a bonded O-Ring using cyanoacrylate or 2-component adhesives. For applications in seawater or other more demanding applications, bonding using a final vulcanization process is required. Use in a vacuum is excluded.
