Hydraulic Cylinder Seal: How Does It Prevent Leakage?

Rod Seal

The rod seal prevents hydraulic fluid from escaping as the piston rod moves in and out.

Piston Seal

The piston seal maintains pressure  between the piston and cylinder, supporting smooth hydraulic operation.

Wiper Seal

A wiper seal keeps dust, dirt, and other contaminants away from the cylinder.

Why Seal Selection Matters

Choosing the right hydraulic seal based on pressure, temperature, speed, and fluid can improve cylinder performance.
