Gearwrench 82171 Tongue and Groove Pliers 12 in 30 Position

Product Description

The GEARWRENCH 82171 is a 12-inch straight-jaw tongue and groove plier built for trade professionals who need a reliable, high-grip adjustable plier for a wide range of fastening and gripping tasks. The V-jaw geometry works with the K9 jaw design to maintain a strong grip even when the tool is positioned at a 35-degree angle. With 30 adjustment positions and a maximum jaw opening capacity of 2.6 inches, this plier handles everything from large nuts and fittings to pipe and conduit work. The alloy steel body provides durability under daily shop and field use, and the dipped vinyl ergonomic handle reduces hand fatigue during extended work sessions.

This plier is suited for residential and commercial service work across plumbing, HVAC, electrical, and general mechanical trades. The straight head style makes it practical in both open and moderately confined spaces. Plumbers reach for this tool when working on supply line fittings and shutoff valves. HVAC techs use it for sheet metal clips, hose clamps, and panel fasteners. The 30-position slip-joint adjustment means fewer tool swaps on the job, and the 12-inch overall length gives enough leverage for most trade applications without being unwieldy in a tool bag.

Installation Notes

No installation is required for this hand tool. Before using on pressurized fittings or live systems, shut off water supply or de-energize electrical components per applicable NEC or IPC guidelines. Inspect the jaw teeth and adjustment mechanism for wear or damage before each use. Do not use this tool as a hammer or pry bar, as doing so can damage the jaw geometry and compromise grip performance.
