The high-performance mechanism generates pressure up to 10,000 PSI, enabling the injection of even the thickest lubricants. For added convenience, it features two-speed settings. To work in hard-to-reach areas, it comes with a flexible 48-inch hose. Fast grease refilling is made easy with a well-designed air release valve system. The handle includes a trigger lock for continuous lubrication flow.
