Crescent Tongue and Groove Pliers HL120PN 20 Inch Utility Wrench (5.5 Capacity 11 Positions Forged Alloy Steel Hardened Teeth Plumbing Pipe Grip)

Crescent HL120PN 20" Straight Jaw Tongue and Groove Pliers

The Crescent HL120PN 20-inch straight jaw tongue and groove utility pliers deliver maximum mechanical turning leverage and heavy gripping power across large-diameter industrial pipes, commercial conduit unions, and heavy machinery fasteners. Forged from high-grade alloy steel with precision-machined interlocking tongue and groove channels, this 4.07-lb adjustable plier provides 11 positive locking jaw positions with an expansive 5.5-inch opening capacity that will not slip under extreme rotational torque. Outfitted with induction-hardened gripping teeth engineered for bi-directional bite, elongated solid steel leverage handles, and rawhide-colored dipped vinyl handles, it ensures non-slip user comfort, high torque transfer, and long-term durability across heavy municipal plumbing, mechanical maintenance, and industrial plant operations.

Best Used For:

• Large-Diameter Mechanical Pipe Fitting: Gripping, tightening, and breaking loose heavy 2-inch to 5-inch black iron, galvanized steel, and PVC drain pipe couplings.
• Industrial Valve and Union Maintenance: Torquing large hex nuts, pump fittings, fire riser flanges, and municipal meter connections requiring high leverage.
• Heavy Machinery and Equipment Repair: Securing irregular round, square, or flat structural stock and hydraulic cylinder caps during plant overhaul tasks.

Key Performance & Safety Features

• 20-Inch Extended Leverage Chassis: Long-reach structural forged handles provide superior mechanical advantage to turn seized, large-diameter industrial fittings with minimal hand strain.
• Machined Tongue and Groove Interlock: Precision-milled ribs lock securely into 11 distinct positions to eliminate joint slipping and handle kickback under maximum clamping load.
• Induction-Hardened Gripping Teeth: Specially angled, heat-treated teeth bite firmly into hardened metal pipe surfaces to maintain sharpness and prevent slippage.
• Expansive 5.5-Inch Jaw Opening: Wide-capacity straight jaw profile accommodates a broad range of round, hexagonal, and irregular industrial workpieces.
• Heavy-Gauge Forged Alloy Steel: Drop-forged carbon alloy steel construction exceeds ASME strength specifications for relentless jobsite endurance.
• Cushioned Vinyl-Dipped Grips: Ergonomic rawhide-colored plastic handles provide a secure, oil-resistant grip and reduce hand fatigue during high-torque turning.

Technical Specifications

Pro-Tip: Position the lower jaw so the direction of force pushes against the forged lower jaw hook rather than pulling away from it; pulling in the direction of the handle rotation directs clamping torque into the interlock channel for maximum bite without jaw spread.
