DESCRIPTION
Our R-5 seal is the Hallite T617 multi-lip rod u-seal.  This seal was specifically developed to meet the requirements of ISO 6020-2 160 bar compact cylinders.  The housing sizes conform to those given for such cylinders in ISO 5597. 
The R-5 seal combines the pressure-compensating, uni-directional characteristics of a u-seal with the multi-lip sealing effectiveness of compression-type stacked packings.  This seal 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. 
Manufactured in the black version of Hallite's high performance Hythane® polyurethane, the R-5 is an extremely flexible seal making installation very easy.  The sealing lips are precision trimmed for consistent sealing performance.
