STEALTH-8 Limited Clearance Torque Wrench, 7984 Ft-Lbs

HYTORC STEALTH-8 is a compact, limited-clearance hydraulic torque wrench from the STEALTH Series, engineered for precise bolting in confined spaces across oil & gas, construction, power generation, and heavy maintenance applications. This low-profile, uni-body design delivers up to 7,984 ft.-lbs. of torque with ±3% accuracy via a simple 3-moving-part mechanism and quick-change cartridges for ratchet or hex links, integrating seamlessly with 10,000 PSI hydraulic pumps for fast, repeatable cycles, enhanced safety through 360° uniswivel hoses and built-in lock-on release, and minimal downtime with no auto-pressure release or cycle counter.
