Two complementary lines covering every project requirement — from ultra-demanding deep-sea metro TBMs to standard utility tunnel drives.
Designed for the most demanding TBM operating conditions. Advanced additive packages deliver superior EP performance, extreme temperature stability, and extended service intervals.
Proven, reliable performance for standard underground applications. The same engineering philosophy as Gold Line, optimised for cost-efficiency on high-volume projects.
High-performance lithium complex grease engineered for TBM main bearing lubrication. Exceptional load-carrying capacity under the extreme radial and axial forces of shield tunnelling.
Multi-component grease sealant system for shield tail void prevention. Maintains an effective barrier against groundwater, compressed air, and grout ingress at the shield-segment interface.
Biodegradable foaming agent designed for EPB TBM face conditioning. Reduces cutterhead torque and wear, controls pore water pressure, and improves muck flow in the screw conveyor.
Premium anti-wear hydraulic fluid for TBM hydraulic systems. Provides superior film strength, rust and oxidation protection, and excellent filterability for precision hydraulic components.
Extreme-pressure grease for disc cutter and scraper tool lubrication. Resists wash-out from groundwater infiltration while maintaining a tenacious film on all cutting tool bearing surfaces.
Water-based mould release agent for pre-cast tunnel segment production. Provides a clean release while protecting mould surfaces and meeting environmental discharge requirements.
Reliable lithium complex main bearing grease for standard TBM applications. Proven performance in metro, road tunnel, and utility projects where operating conditions are well-controlled.
Standard-grade shield tail grease providing reliable sealing performance for low-to-medium water pressure conditions. Compatible with all major TBM shield tail brush systems.
Cost-effective biodegradable foaming agent for EPB conditioning in stable, low-permeability ground conditions. Provides reliable flow improvement and torque reduction at competitive cost.
Our engineering team will review your ground conditions, TBM specifications, and project timeline to recommend the optimal product selection.
