Tail Seal Grease

Normet offers a range of tail seal greases for shielded TBM use that cover first fill, high performance and economic driving grade applications. First fill grade tail seal grease is pumped into the wire brushes before the TBM starts up. Once applied inside the brushes, the first fill grade protects them against wear, water soil and annulus grout ingress while keeping the brushes highly flexible for protect long-term sealing. Driving grade tail seal grease is pumped into the sealant chambers as the TBM advances.
