Today's hydraulic equipment operates at higher pressures and with greater precision than ever before. Although they are able to do more work and are more responsive to operator and automatic controls, they are also more vulnerable to wear and deposit formation caused by the higher operating temperatures and pressures. MAG 1 Hydraulic Fluids are specially formulated with only the finest quality, severely hydrotreated, high viscosity index, paraffinic base oils and the most advanced and rigorously-tested additive systems to deliver unsurpassed protection and performance. Superior Chemistry. Superior Performance.
