Copper bonnet gaskets, commonly called ‘caps’, serve as seals for applications in the refrigeration industry and are suitable for closing pipes temporarily or permanently.
Made of copper and annealed after shearing to increase ductility, they guarantee a reliable hermetic seal and a secure, long-lasting closure.
Technical Information:
Copper Cu 99,9% as per EN 1652
