Seal kit consists of a PTFE rod sealing ring and O-ring, they are combined as a single unit and are appropriate for rods and plungers in hydraulic cylinders. The rod seal is designed to ensure that pressurized fluid does not leak out of the system as the rod cycles back and forth out of the gland. The rod seal is the most critical seal on any type of fluid power equipment. A leaking rod seal not only reduces equipment performance, but also causes environmental issue. Particular attention should be paid to selecting the best rod seal for your appliion. It is important to properly pair the rod seal and the wiper for the best sealing performance. If a less aggressive rod seal is paired with an aggressive wiper, the wiper can scrape off the microscopically thin film of oil that remains on the rod in microscopic surface imperfections during the return stroke, resulting in system leakage. The thickness of the oil film depends upon the surface finish, rod seal and surface speed of the rod.
