Product description

1.Features

Elastomer double-lipped dust ring.

2.Materials

The O-ring is Nitrile Butadiene Rubber (NBR); or Fluororubber (FKM).

3.Performance

The double-lipped dust ring has the oil scraping function of U-shaped seal ring in the inside and the scraping dust function of preventing dirt intrusion in the outside.
Very good for scraping and dust removal, while preventing the residual oil film from sticking to the piston rod.
The positioning of the outer circle is reliable.
The dust ring can be used over a wide temperature range.
The double-lipped dust ring is best used in conjunction with the GSJ and GMSS of the piston rod seal system. We recommend that in all cases, that a pressure relief oil return hole should be opened in front of the double-lipped ring. To prevent back pressure between the seal ring and the dust ring.
