Session 7 focuses on the parts of a hydraulic system that don’t always get much attention—until something leaks, fails, or doesn’t fit. BJ Wagner walks through hoses, tubing, fittings, and reservoirs, showing how these “in-between” components play a major role in system reliability. From proper sizing and identification to installation and selection, the session highlights how small details in fluid conveyance can make a big difference in performance (and headaches avoided).
