Hallite 605 Rod Seal
RTU25-4.00-31 94A Urethane U-Seal | 4 in ID 1/4 in CS
The twin lip design helps solve difficult rod sealing problems by providing lower friction, increased stability, and high, dynamic lip force, while preventing air penetration from outside the cylinder.
Asymmetric rod seal designed with precision trimmed sealing lips to provide a dry sealing solution in light and medium-duty applications. The Hallite 605 is molded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance.
Designed to have interference in the seal housing groove and has a secondary lip. The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The inner dynamic lip is shorter and more robust to improve sealing and compression set characteristics over conventional, symmetrical U-seals. The seal can be considered for use in heavy-duty applications when used with a suitable full depth back-up ring. The sealing lips are precision trimmed at an angle to give optimal rod sealing performance.
