663

- Hallite 663 is a single lip asymmetrical U-ring rod seal designed to provide a dry sealing solution in light to medium duty applications and manufactured in Hythane® 181, Hallite's high performance polyurethane, for ease of installation and excellent low temperature performance. The seal may be considered for use in heavy-duty applications when used with a suitable full-depth back-up ring.
- The seal is a single-lip modification of the well-established Hallite 605 profile and is ideal for applications requiring a dual-lip wiper, such as Hallite 839, Hallite 844, Hallite 846 or Hallite 864. Hallite 663 is also offered in other high quality Hythane® materials to better suit application needs.
