Irwin 2074118 18″ Cast Aluminum Pipe Wrench, 2-1/2-Inch Jaw Capacity

The Irwin 2074118 18″ Cast Aluminum Pipe Wrench is designed for professional tradespeople who need a strong, lightweight solution for turning and gripping pipe in demanding environments. Its heavy-duty cast aluminum construction is 40% lighter than traditional cast iron, making it easier to handle without sacrificing strength. With a jaw capacity of up to 2-1/2 inches, this wrench is well-suited for plumbing, mechanical, and construction applications involving mid-sized pipe. The drop-forged, heat-treated jaw resists distortion under pressure, while hardened teeth provide aggressive grip even on smooth or worn pipe surfaces.

The I-beam handle offers superior strength with better weight distribution, and the integrated hammer head is a practical bonus for knocking fittings or tapping pipe into place. A heat-treated adjusting nut allows for quick, smooth size changes while maintaining durability under jobsite conditions. Whether working overhead, in tight spaces, or on larger plumbing systems, the Irwin 2074118 delivers performance and comfort backed by Irwin’s lifetime guarantee.
