Characteristics and performance
The Hallite 663 is an asymmetric, single lip U-ring rod seal designed to provide a dry sealing solution in light and medium-duty applications and manufactured in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance.
The seal is a single lip modification of the well-established Hallite 605 profile and is ideal for applications that require a double-lipped wiper, such as the Hallite 839, Hallite 844, Hallite 846, or Hallite 864. The Hallite 663 is also offered in other high quality Hythane® materials to best fit the needs of the application.
