PYROGARD 42, 43, 55 Chemical compatibility with O-rings, rubbers, & plastics

Pyrogard 42, 43, and 55 are phosphate ester-based fire-resistant hydraulic fluids used in industrial applications where fire hazards are a concern. These fluids provide excellent lubrication, thermal stability, and oxidation resistance while offering fire-resistant properties. Pyrogard fluids are commonly used in hydraulic systems in steel mills, foundries, and other high-temperature environments. They help prevent the ignition and spread of fires, ensuring the safety of equipment and personnel. Pyrogard fluids also provide protection against wear, corrosion, and deposit formation, extending the lifespan of hydraulic components. Proper handling and disposal are necessary to minimize environmental impact.
