The Benefits of AeroShell Hydraulic Fluids

Optimized Viscosity for Consistent Performance

AeroShell hydraulic fluids maintain stable viscosity across wide temperature ranges, ensuring consistent, reliable system performance from cold starts to high-heat operations and preventing efficiency loss.

Enhanced Lubricity for Extended Component Life

With advanced additives, AeroShell fluids significantly enhance lubricity to minimise wear and tear on hydraulic components, ultimately extending part lifespan and lowering maintenance costs.

Superior Thermal Stability for System Integrity

Engineered to resist oxidation and thermal degradation, these AeroShell hydraulic fluids prevent harmful sludge and deposits, thus maintaining fluid performance and safeguarding system integrity.

Robust Corrosion Protection in Harsh Aviation Environments

AeroShell hydraulic fluids contain specialised additives that provide robust protection against corrosion, crucial for safeguarding metal components in diverse aviation operating environments and ensuring long-term system health.

Uncompromised Compatibility for System Health

Formulated for full compatibility with aircraft hydraulic system materials like seals and hoses, AeroShell fluids prevent damage or degradation, ensuring vital component integrity and reliable system operation.

Product Spotlight: AeroShell Hydraulic Fluids 31 & 41

Aeroshell hydraulic fluids brochure with product tins

Particulates in hydraulic fluids can cause system failures through valve sticking, wear and blockages in nozzles and tubes. Particulates are especially challenging for modern hydraulic systems that operate at high pressures and have components with tight tolerances.

AeroShell Hydraulic Fluids 31 and 41 are formulated to protect hydraulic systems against failure by meeting super-clean standards. Their particulate contents are tightly controlled through special manufacturing processes, including multistage filtration, container cleaning just before filling and clean-room packaging conditions.

Content Spotlight: Introduction to Hydraulic Fluids in Aerospace

Close up of aircraft tyres on runway

Hydraulic systems are found in both commercial and military aircraft, converting pressurised fluids to power a variety of components. To reduce maintenance costs, selecting the right hydraulic fluid is essential, and the following introduction provides an insight into what considerations should be taken when choosing the right fluid.

It is vital that any oil selection is based on the OEM approvals and aircraft maintenance manual instructions. We have put together a downloadable full cross reference guide for hydraulic fluid specifications and approvals.

FAQs about AeroShell Hydraulic Fluids

Is AeroShell 41 the same as 5606?

AeroShell Fluid 41 is essentially the same as MIL-PRF-5606 material, as it’s a mineral hydraulic fluid formulated to meet and often exceed that modern military specification. It is specifically produced to be “superclean” for enhanced system reliability compared to older 5606 fluids.

What is AeroShell fluid 3 used for?

AeroShell Fluid 3 is a light general-purpose lubricating oil recommended for various aircraft parts like hinges, pivot joints, control cables, and instruments. It is also used as a preservative oil for aircraft hydraulic components during storage.

What is AeroShell fluid 41 used for?

AeroShell Fluid 41 is widely used in aircraft hydraulic systems where a “superclean” fluid can significantly improve component reliability. It is designed for systems operating across a broad temperature range, from -54°C (-65°F) to 135°C (275°F) under pressure.
