Hydraulic Oil Booster Stop Leak 4x1 Gallon

The Hydraulic Oil Booster Stop Leak 4x1 Gallon from Lucas Oil is a professional-grade hydraulic fluid additive designed for operators and maintenance teams who depend on consistent system performance in demanding field conditions. This four-gallon package addresses the critical issue of internal leakage that degrades system efficiency and responsiveness, making it essential for keeping equipment mission-ready.

Lucas Oil's formulation targets the root cause of hydraulic performance loss—worn seals and internal wear—rather than masking symptoms. This stop-leak formula works by conditioning elastomer seals and restoring their original pliability, which reduces bypass leakage across pistons, cylinders, and valve spools. Additionally, it reduces viscosity breakdown under thermal stress and enhances film strength between moving components.

Maintenance depots and field mechanics benefit most from the four-gallon bulk format, which economically services multiple applications. Each gallon of concentrate is compatible with ISO 32, ISO 46, and ISO 68 mineral-based hydraulic systems, allowing for use in various mobile equipment and tactical vehicles without requiring complete system flushing or component replacement.
