Crucible lid sealRobco's crucible lid seal is your best solution!


This rope is used to seal the top lid found on tapping crucible in the aluminium industry. It is braided to a specific density to ensure a tight seal, without being too dense to prevent positive closing of the crucible cover. A high temperature resistant coating is applied on the surface to act as heat shield and facilitate rope removal, without any sticking or cleaning required


Our main manufacturing facility is located in the province of Québec where the largest concentration of primary aluminum smelters in the world is located. Our 98 years of service to this industry has enabled us to engineer specific solutions for you.
