Which end of a double-acting cylinder is pressurized to cause extension?

Explanation:
To extend a double-acting cylinder, you pressurize the cap end. Fluid entering the cap end pushes on the piston’s cap face, driving the piston toward the rod end. Since the rod is attached to the piston, this motion pushes the rod outward, producing extension. Pressurizing the rod end would push the piston toward the cap end, retracting the rod. The cap end is simply the end opposite the rod where extension is generated, while the rod end governs retraction.
