Frequently asked
Can Skydrol LD-4 be mixed with MIL-PRF-5606 or other mineral-oil hydraulic fluids?
No. Phosphate-ester and mineral-oil hydraulic fluids are not compatible, and the seals in each system are chosen for one fluid type. Use only the fluid your aircraft maintenance manual specifies.
What should technicians wear when handling Skydrol?
Phosphate-ester fluids irritate skin and eyes, so chemical-resistant gloves and eye protection are standard. Follow the safety data sheet supplied with the fluid.
