DESCRIPTION
The R-5N multi-lip rod u-seal is designed for pneumatic and light hydraulic service. This 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-5N 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-5N is made from 80-durometer Nitrile rubber material ensuring flexibility for installation and high/low pressure performance. For a wider range of chemical media and high temperatures up to 400F, please see our R-5V profile made from 90-durometer Fluorocarbon.
