United Fire-Resistant Hydraulic Oil EFR is a Synthetic Polyol-ester based Hydraulic Fluid. It was developed for severe service in all hydraulic applications where a fire hazard exists and petroleum hydraulic oil would be potentially unsafe. United Fire-Resistant Hydraulic Oil EFR's excellent stability enables it to prolong fire-resistant properties and resistance to the formation of sludge or deposits in prolonged service.

United Fire-Resistant Hydraulic Oil EFR does not contain water, mineral oil or phosphate that blended with high-quality special materials and carefully selected additives. It is a boutique of hydraulic oil. It has a higher flash point than mineral oil-based hydraulic oil to reduce flame spread.

United Fire-Resistant Hydraulic Oil EFR is non-irritating, non-toxic to aquatic organisms, completely biodegradable, and waste easy to handle. It is suitable for use in hydraulic equipment that requires environmental protection. Not only to ensure the environment-friendly but also to affect the overall operation of the hydraulic system performance. It has a longer service life, excellent wear and lubricity with comparing mineral base stock hydraulic oil. Its high Viscosity Index and low pour point make it suitable for application under both extremely warm and cold temperatures.
