Overview of Rod Seal – JENP Oil Seal Manufacturer

The rod seal is the most critical in a cylinder application. It is used in hydraulic cylinders for fluid sealing. They are external to the cylinder head and seal against the cylinder’s rod, preventing leakage of fluid from within the cylinder to the outside. At the same time, it must be protected against external contaminants. Failure of rod seal can result in fluids leaking into the immediate environment and can jeopardize both performance and safety.


The main features of any Rod Seal are:


  • Act as a dynamic seal along its inner diameter, and static along its outer diameter.
  • Directly affected by changes to the rod surface and fluid temperature fluctuations.
  • Often sees the highest pressure variations or spikes in the system.
  • Depending on the level pressure range of the system and the fluid compatibility.
