4TÉ Rock Breaker Grease (400gm) has a unique formula which prolongs the life of the wear parts of hydraulic breakers and hammers. It possesses a high viscosity providing excellent lubrication to the shaft and bushings preventing metal-on-metal contact even under severe operating conditions creating great protection against breakdown, seizures, and galling. Its resilience to high temperatures significantly reduces consumption and prevents unnecessary wastage of lithium-based EP greases commonly used in this application.
