Ingco 18-Inch Pipe Wrench | 450mm Ductile Cast Iron Lever Plumber Spanner with Cr-Mo Mobile Jaw (HPW0818)

The Ingco HPW0818 Pipe Wrench is a professional-grade plumbing and mechanical tool engineered to provide exceptional leverage and gripping power on threaded pipes, couplings, and heavy cylindrical fittings. Measuring 18 inches (450mm) in length, this industrial tool features a wide adjustable throat configuration capable of clamping down securely on workpieces with external diameters up to 60mm.

The plumbing wrench is constructed with a heavy-duty frame made from ductile cast iron, a premium structural alloy chosen for its high tensile strength and ability to absorb extreme twisting forces without bending or fracturing. The critical moving components feature a mobile jaw forged from Chrome-Molybdenum (Cr-Mo) steel that undergoes a specialized induction hardening process (inactivate heat treatment) to optimize tooth durability. The deep-set teeth feature a sharp, backward-angled geometry that cuts through surface scale to bite tightly into round pipes. The jaw faces are finished with a protective black coating and precision polished surfaces, while a solid structural steel rivet secures the internal spring assembly for reliable, non-slip jaw tracking under heavy load conditions.
