Tunnel Boring Machines (TBM) are an example of critical application as seals must absolutely stop any kind of underground contamination and prevent damage to mechanical parts.
 
CARCO manufactures large diameter seals for both Hard Rock and Earth Pressure Balance (EPB) machines.
 
CARCO engineers design the complete seal assembly and suggest solutions to withstand higher pressure levels of challenging tunnelling projects.
 
The biggest CARCOSEAL for TBM has a diameter of 8,5 meter.
