Cat® Hydraulic Hammer Paste (Grease) is formulated to lower friction and improve tool and bushing life in the harsh environments encountered with Hydraulic impact hammer applications. These work tools generate high heat, severe shock, and heavy friction loads, which can fuse parts together. Cat Hydraulic Hammer Paste contains optimized amounts of copper and graphite to provide excellent wear protection even at temperatures higher than 2000°F (1,093°C)
