MGHTO Low-Profile Hydraulic Torque Wrench

MGHTO Series low-profile hollow hydraulic torque wrench is engineered for tightening and loosening fasteners in confined spaces where conventional square-drive tools cannot fit. Rated for a maximum working pressure of 70 MPa, the MGHTO delivers controlled, repeatable torque directly onto the nut through interchangeable closed, open and ratchet drive plates. A single universal drive head accepts all three drive plate styles, so one wrench body covers nut sizes from 27 mm to 120 mm. The compact 360° × 186° swivel body and all-alloy-steel construction make it ideally suited to valve, wellhead (Christmas tree), flange and piping bolting in oil & gas, petrochemical and power generation plants.

Optional Attachment

The MDW square drive hydraulic torque wrench range spans 112 to 72,000 N·m in 11 standard models, with bolt capacity from M14 to M125. A single tool family covers light flange work through heavy structural bolting, so your crew standardizes on one platform with common pumps, hoses and high-strength sockets instead of mixing tools from different suppliers.
