RU Rod U-Cups

High Performance RU Rod U-Cups

Of all the seals in a cylinder application, the rod seal is the most critical. The importance lies in the fact that rod seal failure could result leakage of fluids to the environment, and that it will typically see the harshest service conditions. Rod seal failure is not only a mess, but it is detrimental to proper cylinder performance and safety. The key features of any rod seal are:

  • The rod seal acts as a dynamic seal along its inner diameter, and static along its outer diameter
  • It is directly affected by changes to the rod surface and fluid temperature fluxuations
  • Often sees the highest pressure variations or spikes in the system
