VERSA-4 Low Clearance Power Head, 4503 Ft-Lbs

Hytorc VERSA-4 Low Clearance Power Head is a lightweight, versatile hydraulic torque wrench powerhead from the VERSA Series, delivering up to 4,503 ft.-lbs. of torque for precise bolting in confined spaces across construction, oil & gas, wind energy, and industrial maintenance applications. This ergonomic tool features a simple 3-part design with quick-change cartridges for ratchet or hex links, ±3% accuracy, and seamless integration with electric or pneumatic pumps, enabling fast, repeatable cycles with minimal operator fatigue and safety enhancements like 360° swivel hoses and auto-retraction.
