Professional Grade Adjustable Tongue and Groove High Leverage Pliers

The GEARWRENCH 82167 16-Inch Pitbull K9 V-Jaw Tongue and Groove Pliers are an industrial-grade manual hand tool designed to secure high-torque mechanical connections on oversized fasteners, pipes, and plumbing fittings. Forged from premium alloy steel, this tool features an innovative K9 jaw configuration that delivers a secure mechanical bite even when operating at a 35-degree angle. Featuring a 16.5-inch overall length and a wide 4.2-inch jaw capacity, these pliers optimize downward leverage across 10 adjustable positions, successfully solving the problem of hand slippage and fastener corner rounding during heavy-duty utility and industrial maintenance workflows.

Best Used For:

  • Industrial Pipe Fastening: Gripping and turning large-diameter iron pipes, conduits, and mechanical plumbing fittings without marring or slipping.
  • Stubborn Fastener Extraction: Loosening rounded, frozen, or heavily rusted nuts and industrial bolts that defy standard fixed wrenches.
  • High-Torque Mobile Mechanical Repairs: Operating in tight, off-angle spaces where variable jaw widths and high leverage are mandatory.

Key Performance & Safety Features

  • K9 Jaw Interface Geometry: Patented profile provides an unyielding mechanical grip on workpieces even when deployed at severe 35-degree operating angles.
  • Aggressive Angled Teeth: Hardened, reverse-direction tooth cuts dig into circular, square, or hex stock to prevent tool rotational displacement.
  • 10-Position Tongue Adjustments: Offers ten precise jaw settings to ensure the user can select an ergonomic hand span for maximum clamping force.
  • Integrated Safety Pinch-Stop: Engineered mechanical stop prevents the dipped steel handles from contacting each other, protecting skin from blisters.
  • Visible Dipped Grips: High-visibility molten orange handle covers supply reliable comfort and wipe clean instantly of shop oil and industrial grease.

Pro-Tip: When gripping threaded fasteners or metallic plumbing lines, ensure the workpiece sits deeply inside the V-jaw tracking throat instead of resting solely on the tips of the teeth. This positions the load along the tool's core structural channels, optimizing manual torque delivery and preventing tooth degradation.
