Characteristics and performance

The Hallite 620 is a twin lip rod seal designed with precision trimmed sealing lips to provide a dry sealing solution in light and medium-duty application. The seal is manufactured in a polyurethane shell energized by a high quality O-ring. The sealing lips are trimmed at an angle to give optimal rod sealing performance.

Like the Hallite 621 rod seal, the Hallite 620 is designed to have an interference in the seal housing groove and a secondary lip. The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. At zero or low pressure, the O-ring helps to increase the sealing force preventing any bypass. Under most conditions as the pressure rises, the sealing force increases and the O-ring ensures complete lip actuation. Together these features result in improved life and sealing.

Product details

The Hallite 620’s seal shell is molded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance. The Hallite 620 is also offered in other high quality Hythane® materials to match the needs of the application.
