The hydraulic bottle jack with carrying case is designed for residential and commercial use. It is industrial welded and engineered using a drop forged alloyed steel construction that is ideal for quality and durability. The inner/outer welded structure and steel construction will keep your bottle jack leak-free and give it an overall stronger build. The fully welded structure is designed for hard-hitting commercial use, making large loads easy to lift. A wide, rugged base adds stability and strength. The lifting range is 8-1/2 in. to 16-1/4 in. with a 6-ton (12,000 lbs.) capacity. It features a high-quality glide-action pressure pump designed to lift with minimal muscle and effort and has an integrated built-in oil-bypass and overload valve that protects the hydraulic system from extending beyond its travel limits. Hydraulics are powered with a high-quality oil, which offers better corrosion resistance and high/low temperature flexibility, allowing the unit to operate at temperatures between 40° and 105° F Piston ram utilizes a Y-style polyurethane sealing ring with backup ring, preventing the load from falling slowly. This powerful bottle jack is ideal for lifting cars, trucks, SUVs, farm vehicles, heavy-duty machinery and industrial equipment. Includes a blow mold carrying case making storage and transportation easy. Material: Carbon Steel.
