Three phosphate ester fluids, each with its own strengths. Tell us your aircraft and we will confirm the approved fluid.

Skydrol LD-4 aviation hydraulic fluid
Type IV

Skydrol LD-4

  • Longest fluid life: of any phosphate ester fluid in high and low moisture and temperature conditions.
  • Faster cold starts: density and low temperature viscosity allow up to 25% better hydraulic system efficiency.
  • System reliability: thermal stability and erosion protection at 3000 and 5000 psi.
  • Less waste: longer fluid life means less volume for disposal.
  • Fleet compatible: normal top ups for conversion, compatible with existing Type IV and V fluids.
