Proto J140-12 Internal Pipe Wrench

Product Description

The PROTO J140-12 is an internal pipe wrench designed to grip and turn pipe from the inside diameter rather than the outside. This tool allows technicians to loosen or tighten pipe sections in confined or recessed installations where a standard external wrench cannot seat properly. It is a hand tool used across plumbing, pipefitting, and mechanical trades. At 0.34 pounds, it is a lightweight single-piece tool suited for close-quarters work. Trade professionals select this style of wrench when removing broken pipe nipples or fittings that are flush with or recessed below a surface.

The J140-12 is used in residential and commercial plumbing and pipefitting applications. It is particularly useful when removing a broken or flush-cut pipe stub that has no external surface for a standard wrench to grip. Pipefitters and plumbers reach for internal pipe wrenches during maintenance, repair, and renovation work where standard tooling cannot make contact with the workpiece.

Installation Notes

This tool is typically used by licensed plumbers and pipefitters. Before use, shut off the water supply or process fluid at the nearest isolation valve and relieve system pressure. Insert the wrench body into the pipe bore, expand the gripping mechanism against the inner wall, and apply turning force. Follow applicable IPC and local plumbing code requirements when modifying or removing pipe assemblies.
