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.
