Skydrol 500-B4

The Skydrol 500 series of fluids has the longest service history among phosphate ester products. The first version, Skydrol 500, was introduced in 1952. Steady improvements to the formulation led in 1978 to the current version, Skydrol 500B-4 which contains the same breakthrough anti erosion additive and acid scavenger found in Skydrol LD-4 . Skydrol 500B-4 is the most worker friendly of the aviation phosphate esters; it is least irritating to skin and less prone to form mists which can be irritating to the respiratory tract . This has given the product enormous popularity for use in work shops and indoor test stands.

Skydrol LD-4

Skydrol LD-4 was also introduced in 1978, and is today the largest selling aviation phosphate ester fluid in the world. At the time of its introduction it was a breakthrough product, solving problems of valve erosion and thermal stability common in earlier fluids. Its excellent thermal stability under real world conditions has given it a reputation as the gold standard among Type IV fluids. In recent years it has received an additional qualification of 5000 psi approval under Boeing BMS 3-11 (Type V, Grade B and Grade C). Skydrol LD-4 features low density, excellent thermal stability, valve erosion prevention, and deposit control.

Skydrol 5

Introduced in 1996, Skydrol 5 was the first Type V fluid qualified under the Boeing BMS 3-11 specification. Skydrol 5 offers higher temperature capability than Type IV fluids, the lowest density, and better paint compatibility. Skydrol 5 does not have universal air frame manufacturer approval, so please consult Solutia's Skydrol Technical Service (800-260-4150) for specific approval and application information.

Skydrol PE-5

Our newest product, Skydrol PE-5 is currently undergoing flight service evaluations with various air frame manufacturers. Skydrol PE-5 was developed to meet the latest Type V hydraulic fluid requirements, the "harmonized" fluid specifications from Airbus, Boeing, and the fluid manufacturers. Skydrol PE-5 features the longest fluid life of any commercially available fluid, low density and low viscosity at low temperature; an unbeatable combination of the best features for optimum fluid performance.

MCS 352B

This product is a viscous assembly lubricant for components and equipment designed to use Skydrol aviation hydraulic fluids. Approved by airframe manufacturers, MCS 352B lubricates seals during assembly, preventing them from being damaged. It introduces no foreign material into the hydraulic system because it contains no silicone oils, nor any petroleum based products.

MCS 2361

This product is not used in aviation, but is an industrial phosphate ester fluid. It is used in fire department rescue equipment, where fire resistance is an essential attribute.
