S2A WIPER SEAL
The function of the S2A type rod wiper is to prevent introduction of dust, dirt and foreign material inside the sealing system. This scraper can exert an effective action additional seal when used with a rod seal with good return characteristics hydrodynamic.
Features
• Low static and dynamic friction
• High speeds allowed
• No “stick-slip” tendency
• Small footprint and simple execution of the site
• High compatibility with all fluids (with right choice of O-Ring material)
• High temperature resistance
