Ridgid 342 Internal Pipe Wrench

The Ridgid 342 is an internal pipe wrench built for plumbers and maintenance technicians who need to grip and turn pipe from the inside. Its alloy-steel body and eccentric-action jaws expand to fit a range of internal diameters and can be reversed to suit different sizes. The tool measures 4 1/2 inches in length and weighs 1.62 lb, making it compact enough for tight access points while still delivering strong torque. It is intended for professional pipe installation and removal tasks.

Replaces fixed-size internal wrenches

This wrench replaces a set of fixed-size internal wrenches by covering multiple pipe diameters with one adjustable tool. The jump is worth it when you regularly work on various pipe sizes and want to reduce the number of tools carried to the job site. The reversible jaw design allows quick adaptation without swapping tools, saving time on service calls and renovation projects where pipe dimensions vary. It is not for buyers who only ever work on a single, known pipe size.

Simple hand-tool operation

No assembly or power source is required; the wrench is ready to use straight from the box. Insert the jaws into the pipe, turn the adjustment to expand them by eccentric action, and apply torque with a wrench or ratchet on the drive end. What usually goes wrong is applying excessive force on undersized pipe, which can deform the jaws or damage the pipe interior. Always ensure the jaws are fully engaged and reversed correctly for the pipe size before applying load.
