Design Description：

SRD is a double lip metal frame dust ring. It is firmly bonded by polyurethane dust ring and a metal framework after nitriding and rust prevention treatment. The polyurethane dust lip can collect the medium passing through the piston rod seal after precise trimming, and the specially designed dust lip can improve the sealing performance of the rod. 

The polyurethane dust lip can move laterally with the piston rod, thus scraping out serious sediment pollutants. It is an ideal choice under high pollution conditions and improves the service life of the sealing system.
