DESCRIPTION
The R1-LF is ideal in situations that require a low friction seal. The multi-lip metric 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 R1-LF is made from premium urethane material ensuring flexibility for installation and high/low pressure performance.
