Hydraulic Fluids

Aerospace hydraulic fluids transfer power and lubricate critical aircraft systems. GracoRoberts offers hydraulic fluids, specialty greases, and oils for commercial, military, and general aviation aircraft. These products are selected to support pumps, actuators, and valves under high load, temperature shifts, and other demanding operating conditions.

Aerospace-Grade and Military-Spec Lubricants

You want the best for your aircraft, which is why we provide top-tier lubricants like Castrol Braco Braycote 236, a high-performance grease designed for extreme environments. We also offer Armite VV-P-236, a military-grade lubricating oil known for its excellent wear protection, and Aervoe Crown 3452 Mold Release Lubricant. Our aerospace-grade formulations meet the highest industry standards, like MIL-L-23398, so you can shop with confidence.

Understanding the differences between hydraulic fluid types can help you choose the right product. Mineral-based fluids are used in some legacy systems, synthetic fire-resistant fluids serve many military applications, and phosphate-ester fluids such as Skydrol are widely used in commercial aircraft. Always confirm the aircraft maintenance manual or OEM specification before changing fluid families.

Our catalog also includes a wide selection of aerospace hydraulic fluids designed to perform under high pressure and in variable temperatures. These products act as both a power transfer medium and a lubricant, protecting pumps, actuators, and valves from wear and corrosion. Our hydraulic fluids are formulated to meet VV-L-800 and P 236 specs and offer dependable stability in both commercial and military aircraft systems. Skydrol 500B-4 Fire Resistant Hydraulic Fluid is a phosphate-ester option for fire-resistant applications and anti-corrosion performance.

High-Performance Oils and Greases

Sometimes, the occasion calls for a high-performance oil or grease. For times like those, we suggest 1010 Oil, a high-quality lubricant that provides outstanding corrosion resistance and performance in high-friction environments. Our selection also includes options for extreme temperature and vacuum applications. Whether you're maintaining turbine systems, landing gear or actuating mechanisms, our grease and oil products deliver exceptional results. Need something you know will last? Lubricants labeled MIL-PRF-46010 and MIL-PRF-6081 meet rigorous military performance standards, ensuring durability and efficiency in demanding conditions.

For operations requiring bulk supply, many of our lubricants and hydraulic fluids are available in 220 L drums or 220 litre containers to support high-volume maintenance and manufacturing needs.

Industry Compliance and Reliable Performance

Our lubricants are designed to meet all industry standards to ensure reliable performance and consistent results. Whether you need high-temperature resistance, anti-corrosion protection or extreme pressure performance, GracoRoberts has the right lubricant for your needs. Browse our selection today to find the perfect solution for your application. From maintaining fluidity in sub-zero conditions to delivering consistent viscosity under high load, our products meet critical aviation demands.

High-pressure hydraulic systems demand careful fluid selection. Before changing fluid families, buyers should confirm seal, hose, and paint compatibility, especially with phosphate-ester options such as Skydrol 500B-4 Fire Resistant Hydraulic Fluid. For maintenance and procurement teams, many lubricants and hydraulic fluids are also available in 220 L drums or 220 litre containers.

Whether you're sourcing VV P 236 hydraulic lubricants, general-purpose oils or mission-critical MIL-SPEC fluids, GracoRoberts offers an unbeatable mix of quality, compliance and support. Browse the selection today to find the perfect solution for your aircraft.

Frequently Asked Questions About Hydraulic Fluids

What do VV-L-800 and P 236 mean?

They are specification references used to identify certain hydraulic fluid requirements. The aircraft maintenance manual or OEM spec should always confirm the correct fluid family for the system.

Why are phosphate-ester fluids like Skydrol mentioned here?

Phosphate-ester fluids are a common fire-resistant option for commercial aircraft hydraulic systems. They are called out here because they are one of the main fluid families buyers may compare on this page.

What information should I have ready when I request help selecting a hydraulic fluid?

Have the aircraft type, the current fluid spec, and the packaging format you need ready. That helps narrow the right product family more quickly.
