Rod Seals

Rod or Gland seals prevent fluid leakage from the past the rod and into the atmosphere. Rod Seals are one of the most critical devices in a hydraulic system and are necessary to ensure pressure is maintained in hydraulic circuit, maximum force can be held on the rod and that fluid is not escaping the system.
In Heavy-Duty applications, a Rod Seal will be paired with a Buffer Seal. A buffer seal is housed in the gland, between the Rod Seal and the Piston and is used to prevent damage to the primary Rod Seal during instances of extreme pressure and pressure spikes. Xerkin’s seal with an integrated anti-extrusion ring is one of the best Buffer Seal solutions for cylinders operating in extreme environments.
