What seals are not compatible with Skydrol?

What seals are not compatible with Skydrol?

Petroleum oil hydraulic system seals of neoprene or Buna-N are not compatible with Skydrol® and must be replaced with seals of butyl rubber or ethylene-propylene elastoiners.

What is phosphate ester hydraulic fluid?

Phosphate esters have good thermal stability, excellent boundary lubrication properties, low volatility and fair hydrolytic stability (chemical stability in the presence of water). The triaryl version of the phosphate ester is relatively unique among hydraulic fluids because it’s self-extinguishing.

Is Buna-N compatible with Skydrol?

What Seals are compatible with Skydrol? Elastomers are the big issue. Don’t get it wrong. Nitrile, Buna-N, silicone, fluorosilicone and Viton fluorocarbon are totally unsuitable.

Is Skydrol a carcinogen?

4.2 Most important symptoms and effects, both acute and delayed: Eye may become red, tear, and become painful. The product contains a small amount of sensitizing substance which may provoke an allergic reaction among sensitive individuals. Limited evidence of a carcinogenic effect.

Why is hydraulic fluid so toxic?

Swallowing one of the oily hydraulic fluids, like the synthetic hydrocarbons, is potentially dangerous. These products have a tendency to get into the airway more easily than water-based substances. Used hydraulic fluid can contain metal fragments and waste materials collected during the time of use.

What is the main advantage of a phosphate ester base hydraulic fluid over a mineral base fluid?

Phosphate esters are the most fire resistant of the non-aqueous synthetic basestocks in common use. Their high ignition temperatures, excellent oxidation stability and very low vapor pressures make them difficult to burn, while their low heats of combustion result in self-extinguishing fluids.

What is Viton not compatible with?

It is a synthetic rubber that resists many hydrocarbons, biodiesel, and petro chemicals, but is NOT compatible with ketones. Do not use Viton with acetone, esters, amines, organic acids, acetic acid, MEK, ethyl acetate, highly polar chemicals, etc.
