Caps for metal containers

4s® Closure System

For over 100 years, steel drums fitted with Tri-Sure® closures have set the international standard, and they continue to do so. The innovative Tri-Sure® 4s® double washer system creates an "airbag" for your drum. Each metal flange is fitted with two rubber washers to prevent leakage more effectively.

The Tri-Sure® 4s® double washer system also helps protect the contents of the drum from contamination. The double washers act as a seal, preventing the entry of air, dust, and other contaminants. Also, the washers help reduce the risk of corrosion by providing a barrier between the metal drum and its contents. The washers also provide a cushioning effect, helping to protect the contents from impact and vibration. By using the Tri-Sure® 4s® double washer system, companies can ensure the safety of their products and extend the life of the drum.
