Combination Double Ball Check: For Service to 10,000 PSI

All Categories

Combination Double Ball Check

The Combination Double Ball Check Injectors are high-pressure industrial lubrication components engineered for dual-purpose lubricant or stick injection up to 10,000 PSI. They feature a dual-layer check system utilizing two independent ball and spring mechanisms to provide complete redundancy against hazardous fluid backflow. The design is built with a heavy-duty radial rivet crimp, interfaces perfectly with standard button head grease gun couplers, and features integrated hex profiles ranging from 7/8″ to 1-1/8″ for reliable torque application.
