VICAIRE - Module 3 - Chapter 4

Due to the fact that there is no water movement in the capillary tube, the hydraulic head in B is equal to the hydraulic head in A: H B = H A = 0 or z B + h B = 0. Consequently, the pressure head in the point B is negative: h B = -z B. The pressure in the point B will be: p B = -ρg. The same phenomenon occurs above the water table in the capillary fringe.

The ultimate guide to hydraulic cylinders | Hydraulics Online

The hydraulic cylinder head is fitted with seals to prevent the pressurised hydraulic oil from leaking past the interface between the rod and the head. This area is called the rod gland. It often has another seal called a rod wiper which prevents contaminants from entering the hydraulic cylinder when the extended rod retracts back into the cylinder.
