Full Product Description

The GS Ultrathan® rod seal is a U-ring with interference fit on the outer diameter. It has been developed specifically for the exacting requirements of gas spring applications, which – in addition to small grooves – are long service life and maximum gas tightness. The short seal contact area ensures minimum friction. In addition to gas spring applications, these properties make this seal suitable for use in hydraulic and pneumatic equipment with identical requirements profiles.

• Good wear resistance.
• Easy installation.
• High temperature resistance in case of suitable compound selection.
• Excellent media resistance in case of suitable compound selection.
• Suitable compounds available for special requirements of the chemical process industry.
• Suitable compounds available for special requirements of the food processing industry.
• Installation in closed and undercut housings.

Range of application:
The GS rod seal is particularly well suited for gas springs, piston rods, spindles and valve lifters as well as for slow-running rotary distributors (v ≤ 0.2 m/s).
