YK hollow hydraulic wrench maximizes the use of high-strength lightweight metal and integrated power head, comprehensively improving strength and service life; High torque/weight ratio, double acting, high-speed, large turning angle, high efficiency. One power head can be used with multiple working heads, with a wide working range. The 360 °× 360 ° rotating hose joint makes it easy to use in a small space and will never cause the mechanism to get stuck. The torque repetition accuracy is as high as ± 3%, and no other tools are needed when loosening. The storage box protects the wrench head from damage, immersion, and contamination, with fewer moving parts, durability, and easy maintenance.

YK hollow hydraulic wrench has a small volume, high torque, and accurate pre tightening. It is widely applicable to mechanical equipment and facilities in industries such as metallurgy, power, chemical, machinery, and communication. It can be used for the installation, disassembly, and maintenance of important bolt connections, and can easily and quickly complete your bolt installation and disassembly tasks while effectively ensuring the torque value you need.
