Irwin Industrial Tool Co 274103 Cast Iron Pipe Wrench 18in

Product Description

The IRWIN INDUSTRIAL TOOL CO 274103 is an 18-inch cast iron pipe wrench built for heavy-duty plumbing and pipefitting work. The housing and handle are constructed from high-grade cast iron, with a wide I-beam handle design that improves weight distribution during extended use. The drop-forged jaw is heat-treated to resist distortion and breakage under load, and the hardened teeth deliver a firm, reliable bite on pipe and fittings. A unique hammer-head design adds a flat striking surface, giving installers an extra function without reaching for a separate tool.

This pipe wrench is suited for residential and commercial plumbing installation, industrial pipefitting, and general mechanical work wherever threaded pipe connections are made or broken. The easy-spin adjusting nut is also heat-treated for long-term durability and smooth operation under field conditions. Licensed plumbers, pipefitters, and mechanical contractors will find this wrench appropriate for both rough-in and finish work on ferrous and non-ferrous pipe.

Installation Notes

This tool is typically used by licensed plumbers and pipefitters working under IPC or applicable local mechanical codes. Always ensure the adjusting jaw is properly seated and fully engaged on the pipe before applying torque to prevent jaw slippage or pipe damage. Inspect the teeth and jaw condition before each use and replace the wrench if cracks or deformation are visible in the casting.
