Extreme Pressure Fluid

EPF 262 is a synthetic hydraulic fluid suitable for use at pressures up to and in excess of 200,000 psi

Features:

Good compatibility with nitrile seals
Good lubricity
Low viscosity
Low flammability
Very low chemical reactivity
Electrically non-conductive
Non-corrosive, non-hygroscopic
Non-hazardous

EPF 262 is a clear liquid similar to a light hydraulic oil. Unlike oils, which solidify at about 80,000 psi, EPF 262 remains liquid at pressures in excess of 200,000 psi.

EPF 262 has none of the drawbacks common to most other fluids used at high pressures, such as poor seal compatibility, high flammability or promotion of corrosion.

EPF 262 type fluid, also formerly known by the old trade name Plexol 262*, has been used successfully at very high pressures for many years.

Available in:

One gallon bottles
Five gallon pails
Fifty-five gallon drums
