Xpandable steel Patch V-Zero (V0)

Some applications require remedial operation with maximum sealing efficiency with high gas pressure. Performing a gas-tight sealing is a big challenge compared to a watertight solution. Our solution was designed to reach the ISO 14310 V0, ie, the most rigorous criteria of this standard.

In addition to our labyrinth sealing system, available on standard patch range, we developed a dynamic sealing system allowing the elastomer seal to auto-energize with differential pressure. The result is a gas-tight patch capable of sealing with both internal and external pressure, through temperature cycles.
