Western 49311 Hydraulic Fluid optimizes the operating efficiency of your snow plow hydraulic system. Additionally, Western formulates this high-performance oil to withstand extreme winter weather. This premium formula prevents oxidation and thermal breakdown during heavy plow usage. Consequently, your internal pump components experience less wear and tear. Because of this, professional fleet operators choose only original factory fluids.
This convenient 1-quart bottle is perfect for quick field top-offs. If you open a cylinder for a seal repair, you must replenish the reservoir. Furthermore, carrying a spare quart in your truck cab ensures you are never stranded during a major blizzard. This anti-foaming formula releases air bubbles rapidly. Therefore, your lift rams and angling cylinders maintain immediate response when clearing dense snow banks.
