RAVENOL ESF Extra Servo Fluid is a synthetic special hydraulic fluid. Due to its special formulation the properties of RAVENOL ESF Extra Servo Fluid are crucial. We assure an excellent cold stability.
RAVENOL ESF Extra Servo Fluid is designed for use from -50°C to +110°C and is therefore recommended for the latest developments in the vehicle market.
RAVENOL ESF Extra Servo Fluid has an optimal performance behaviour as central hydraulic oil in power steering, rear axle steering, level control, hydro pneumatic suspension, shock absorbers, for active damping and engine protection, for hydrostatic drive of fan, alternator and air conditioning, for stability and traction systems (ABS/ASR/ASC), central locking, electro-hydraulic convertible top control, hydraulic brake booster and hydro pneumatic suspension for VW, Audi, Seat, Skoda. Especially to be used in cold countries.
- Extremely low pour point
- Improved viscosity and coefficient of friction behaviour
- Very good wear protection
- Excellent thermal stability
- A good foaming behaviour
- Neutral behaviour towards sealing materials
- Reliable protection against corrosion
