DESCRIPTION

The R-5 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. The R-5 style 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.

The R-5 is made from premium urethane material ensuring flexibility for installation and high/low pressure performance.
