Abstract: An industrial machine includes a frame supporting a fluid source and a boom, an arm, an attachment coupled to the arm, a cylinder, and a rod. The arm is movably coupled to the boom for translational and rotational movement relative to the boom. The cylinder includes a first end and a second end, and the cylinder defines an internal bore in fluid communication with the fluid source. The rod is coupled to the arm and is slidably received within the cylinder. The rod includes a port and a passage for providing fluid to the attachment. The port provides fluid communication between the internal bore and the passage. The port is positioned within the internal bore throughout the entire range of movement of the rod relative to the cylinder.
