Ridgid RIG31040 Heavy-duty Straight Pipe Wrench 48 Inch

Product Description

The RIDGID RIG31040 is a heavy-duty straight pipe wrench built for demanding trade applications. Constructed with a cast-iron housing and an I-beam handle, it delivers the rigidity needed for high-torque work on large-diameter pipe. The full-floating forged hook jaw self-adjusts to maintain grip, and self-cleaning threads keep the adjustment mechanism operating smoothly under jobsite conditions. At 48 inches overall length and rated for pipe up to 6 inches in diameter, this wrench is sized for large commercial and industrial piping work. Both the hook jaw and heel jaw are replaceable, extending the service life of the tool. Plumbers, pipefitters, and mechanical contractors are the primary users of this tool.

This wrench is designed for use on large-diameter steel, iron, and similar rigid pipe installations encountered in commercial plumbing, mechanical, and industrial piping systems. The 48-inch handle provides the leverage needed to break loose heavily corroded fittings or make final tightening passes on large threaded pipe joints. Its straight configuration suits standard in-line pipe work where offset or end-pipe access is not required. The replaceable jaw design makes field jaw swaps practical without replacing the entire wrench body.

Installation Notes

This tool is typically used by licensed plumbers and pipefitters working on threaded pipe systems. Always ensure a stable footing and secure body position when applying force on a 48-inch wrench, as the leverage generated can be significant. Inspect hook and heel jaw teeth before use and replace worn jaws to prevent jaw slip under load. Work in accordance with applicable plumbing codes, including IPC provisions for threaded pipe joints.
