658 Rod Seal

The Hallite 658 asymmetric twin lip rod seal designed to provide a dry sealing solution in light and medium-duty applications.

The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The Hallite 658 is designed to replace an O-ring and one backup sealing arrangement and offer a much higher level of sealing performance and durability without having to change the seal groove.

The Hallite 658 is molded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance. The Hallite 658 is also offered in other high quality Hythane® materials to match the needs of the application.
