A typical rotary shaft seal consists of several key components a flexible sealing lip, a rigid outer casing, and sometimes a spring mechanism to enhance the sealing effect. The sealing lip is made from elastomeric materials, which allow it to maintain flexibility while adapting to the surface of the rotating shaft. The outer casing is usually made from metal or hard plastics, which ensures a secure fit within the housing or bore.

2. Contamination Control Besides maintaining pressure, seals also protect the internal components from dirt, dust, and other contaminants that can enter the cylinder. A robust sealing system ensures that these foreign particles do not compromise the cylinder's functionality, which can drastically affect the overall performance and lifespan of the hydraulic system.

3. Durability TCN oil seals are designed to withstand a broad range of temperatures, typically from -40°C to +100°C (-40°F to +212°F), depending on the specific formulation of the nitrile rubber. This temperature resistance ensures that the seals maintain their integrity and functionality over a prolonged period.

In addition to preventing fluid leakage, hydraulic piston seal kits also help to protect the piston and other components of the hydraulic system from wear and damage. The seals act as a barrier against contaminants such as dirt, dust, and debris that can compromise the performance and longevity of the system. This helps to prolong the lifespan of the hydraulic equipment and reduce the need for costly repairs and maintenance.
