DESCRIPTION
**AeroShell Fluid 41** is a highly refined mineral hydraulic fluid manufactured to exceptional cleanliness standards.
It provides **excellent low-temperature performance**, **strong anti-wear protection**, and **robust corrosion inhibition**, making it suitable for demanding aircraft hydraulic systems, particularly landing gear operations.
Its high viscosity index and stable formulation support consistent performance across a wide operating temperature range, and its cleanliness contributes significantly to long component life and system reliability.
---
## Applications
- Hydraulic systems in modern civil and military aircraft
- Landing gear hydraulic systems
- Systems requiring “superclean” mineral hydraulic fluid
- Components with synthetic rubber seals (not suitable for natural rubber)
- Industrial and automotive systems requiring a MIL-PRF-5606-type fluid
**Operating temperature ranges:**
- **Unpressurised systems:** –54°C to +90°C
- **Pressurised systems:** –54°C to +135°C
Compatible with **AeroShell Fluids 31, 61 and LGF**.
