The Torin AT95007B hydraulic bottle jack is a durable and versatile tool suitable for both residential and commercial use. Constructed with drop forged alloyed steel, its industrial welded inner/outer structure ensures leak-free performance and a longer operation life compared to traditional screw jacks. The fully welded structure and wide, rugged base make it ideal for lifting heavy loads. With a lifting range of 11 in. to 17-3/4 in. and a 50 ton capacity, it can lift cars, trucks, SUVs, farm vehicles, heavy-duty machinery and industrial equipment. The integrated built-in oil-bypass and overload valve protect the hydraulic system, while the Y-style polyurethane sealing ring prevents load from falling slowly. Additionally, it features a high-quality, glide-action pressure pump that requires minimal effort to lift. Powered by high-quality oil, it offers better corrosion resistance and high/low temperature flexibility, making it ideal for use in military, agricultural and industrial environments where the equipment receives heavier abuse. Material: Carbon Steel.
