Wiper Seals | Scraper Seals
Advantages Wiper Seal
- Small installation grooves.
- Minimal break-out and dynamic sliding friction. Therefore no stick-slip. Steady movement is guaranteed even at low velocities.
- Excellent sliding properties.
- High wear resistance, therefore long service life.
- High temperature resistance.
- Compatibility with nearly all media due to the high chemical resistance of the rod sealing ring, and a wide selection of O-ring compounds.
- Available in diameters up to 1500 mm.

Alternatives
Back-up Rings
Back-up rings are used for static and dynamic applications in connection with O-rings, to prevent extrusion of the O-ring into the diametrical clearance.
Rotary Seals
Rotary seals are used in applications with oscillating or rotating movements in order to retain liquid lubricants and to prevent the penetration of dirt and water.
Rod Seals
The Rod Seal consists of a single-acting PTFE rod sealing ring and an O-ring. They are combined as a single unit and are appropriate for rods and plungers in hydraulic cylinders.
