Hi Hawk21, Buzz here. The barrel in our lube-room says "Chevron Hy-Jet IV". I wonder what the difference is between that and Skydrol 5?
I few years ago i figured out the reason the Skydrol series of hydraulic fluid hurts - even though it's supposed to be inert to your body. It's made to absorb moisture and keep the hydraulic system from corroding. So... it's abosrbing moisture out of you, thus the burning sensation. My remedy for the burn is to rinse with water, rinse with milk, apply castor oil.
I had to explain the Material Safety Data Sheet to the family doctor. It -says- it's inert, but it sure hurts.
g'day and Good New Year

Hyjet IV and Skydrol (LD-4 and 500B4) are interchangeable phosphate ester fluids, made by different manufacturers - both meet BMS-3-11 and AS1241 type IV specifications. But Type V has not been released yet - see my earlier post. It will be better than type IV at higher pressures (5000 psi) and temperatures. I just noticed I said Aerojet in my earlier post -- sorry, it's Hyjet.
When you work in a hydraulic lab, you quickly learn not to touch sensitive body parts without first thoroughly scrubbing your hands.
