The Fast and Permanent Solution for Leaks and Other Emergency Repair

This maintenance and Repair Kit contains a COLDWELDING SYSTEM® capable of repairing leaking tanks, pipes and containers in 3 to 4 minutes.

Virtually any durable material can be quickly and permanently repaired, even while the surface is wet, oily or greasy. Unlike other products on the market, DURMETAL® Super CA-HD Rapid® works under water or in oil. Capable of stopping leaks. DURMETAL® Super CA-HD RAPID® can be used without shutting down systems.

When welding, soldering or brazing is impossible or where explosion and fire hazards are present, DURMETAL® can make that difficult repair.

Heating and air conditioning systems, radiators, fuel and steam lines are repaired while on line. Because DURMETAL® Super CA-HD RAPID® adheres to oily, greasy or wet surfaces, actively leaking systems can be repaired with literally no system downtime.

Repairs with DURMETAL® are permanent and durable, usually saving the costs of new parts or materials.
