HHW Series Low-Profile Hollow Torque Wrenches
Engineering Overview & Structural Features
The HHW Series Low-Profile Hollow Hexagon Hydraulic Torque Wrenches deliver 228 to 44,593 N·m across bolt hexagon sizes from 19 mm to 175 mm (3/4" to 6-7/8"). Engineered with an ultra-slim nose radius and modular hexagon cassettes, providing robust cyclic bolting capability for limited-clearance pipe flanges, pressure vessels, and narrow casing channels.
HIGH-TECH INTEGRALLY MOLDED AEROSPACE BODY
Monolithic aerospace alloy housing strengthens structural rigidity, optimizing power-to-weight ratio and maximizing cyclic bolting service life.
INTERCHANGEABLE HEXAGON RATCHET CASSETTES
Wide range of metric and imperial interchangeable hexagon cassettes (19 mm to 175 mm) swap effortlessly with the drive cylinder without specialized tools.
360° SWIVELING INLET PORT
Dual-axis free-rotating hydraulic manifold eliminates hose kinking and allows comfortable hose routing around complex piping arrangements.
3D CAD OPTIMIZED PRECISION (±3%)
Engineered using 3D CAD modeling to balance stress distribution, delivering consistent torque repeatability within ±3% across the entire pressure envelope.
OEM Cross-Reference & Dimensional Interchangeability
The HHW Series 700 Bar low-profile hollow hexagon torque wrenches deliver 228 to 44,593 N·m across 19 to 175 mm hex sizes with ±3% precision, titanium-aluminum alloy body, and 360° swiveling inlet port. 228 - 44593 Nm / 19-175mm Hex.
