SERDES U-SEALS

Serdes U profile lip seals are designed to maintain water-tightness around working precision mechanics with alternating translatory movement. They can be used on hydraulic and pneumatic devices working with a pressure ranging from a few hundred grammes to 600 kg/cm² with the appropriate profile...
In certain cases higher pressure levels can be reached but need a special study to be carried out.
These seals are classed and referenced in 3 profiles.		 Compared to other types of fittings, lip seals present a number of advantages :

1 - Reduced friction compared to O-rings, with a complete erradication of the start-up friction observed on O-rings.
2 - A perfect collar span reducing risk of extrusion.
3 - Possibility of reduced tightness adjustments for other fitting types.
4 - Excellent grase-scraping factor, important for shaft outlets.
5 - Possibilities of closed-neck mounting as with O-rings.
6 - Excellent user safety.
