Feature Highlights: 1. 3-Way Grease Loading – Works with standard 14 oz. cartridges, bulk suction fill, or direct bulk loading for flexible use. 2. Durable Steel Tube Cartridge – Built with a heavy-duty steel tube for long-lasting performance, weighing 1400g for solid handling. 3. Leak-Resistant Design – Low-variance inner diameter prevents grease leaks during bulk filling, while an O-ring sealed high-pressure piston keeps the pump head leak-free. 4. Secure & Comfortable Grip – Features a non-slip rubber handle for better control and higher grip friction, even during extended use. 5. Complete Hose & Nozzle Set – Includes an 18-inch reinforced flexible hose with spring guard and coupler, a 5-1/2 inch hard metal extension tube, and a pointed nozzle for precise application. Product Details: This manual grease pump is built tough for high-pressure lubrication tasks, supporting up to 8000 PSI when used with a pistol grip handle. It loads grease three ways—via cartridge, bulk suction, or direct fill—making it versatile for shop or garage use. The steel tube cartridge ensures durability, while the sealed piston and precision-fit design prevent messy leaks. The comfortable non-slip handle gives you a firm hold, and the included hose, extension tube, and pointed nozzle help you reach tight spots easily. Ideal for automotive, machinery, and equipment maintenance.
