Rod Seals

Rod seal with a hard, split backup ring on each side of the sealing element. Fits a standard o-ring groove. Non-spiraling and extrusion resistant up to 5,000 psi with improved tolerances.

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. 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. 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.

The HMU style multi-lip rod u-seal combines the pressure-compensating, uni-directional characteristics of a u-seal, with the multi-lip sealing effectiveness of compression-type stacked-packings. Made from premium materials, the, HMU utilizes several sealing lip edges for dry rod performance while minimizing friction. The multi-lip design maintains, a critical sealing edge even though increasing pressure moves the line of contact down toward the heel.
