Wiper, Type AS 01
The wiper type AS 01 consists of an PTFE profile ring and an O-ring as a preload element. The wiper function is taken over by the PTFE profile ring with the seal lip of the profile ring wiping impurities from the retracting piston rod.
These wipers are suitable for use with mineral oil-based hydraulic liquids, environment-friendly bio-oils and water and even with flame-resistant hydraulic liquids and air. The wipers provide very good gliding behavior and stick-slip free running, good dry-running properties and high wear resistance.
- Mineral oil-based hydraulic liquids
- Environment-friendly bio-oils
- Flame-resistant hydraulic liquids
- Other media, depending on the O-ring material

PTFE profile ring material
PTFE + bronze
The standard for hydraulic applications, good gliding behavior, particularly pressure and abrasion resistant, cannot be used in aqueous solutions or acids
PTFE + Glass-MoS2
Particularly wear and abrasion resistant, can be used even with poorly lubricating pressure media, in water and also in water-oil emulsions
PTFE + carbon
Exceptional resistance to abrasion and extrusion; can be used in water-hydraulics
For other possible materials see our overview of PTFE materials in the technical information section.
Nitrile rubber NBR: Temperature range − 30 °C to + 120 °C
Fluororubber FPM: Temperature range − 25 °C to + 200 °C
