DesignThe result of many years testing and development, the Hallite 609 rod seal is truly a breakthrough in pneumatic sealing. The Hythane 181 material and the profile of the dynamic sealing lip combine to offer both ultra low friction - significantly less than that of rubber - and ultra long life.The Hallite 609 has been developed to give significant improvements in cylinder performance in low lube air conditions and be used in long and short stroke applications.
