12 in Non-Sparking Tongue & Groove Plier
The Ampco P-312 is a 12 in tongue and groove plier made from nickel aluminium bronze. Its non-sparking and non-magnetic properties suit maintenance in hazardous environments where ferrous tools pose a risk. The flat, serrated jaws provide grip on pipes, fittings and fasteners without damaging softer materials. Six groove-joint positions allow a maximum jaw opening of 2 1/8 in for versatile adjustment.
Thermals Noise and Power Draw in Normal Use
As a non-powered hand tool the plier generates no heat, noise or electrical draw during operation. The uncoated bronze alloy resists corrosion without requiring lubrication or external cooling. Manual force is the only energy input, so there are no thermal limits or duty-cycle constraints to manage. The standard cushion grip reduces hand fatigue during prolonged twisting or clamping tasks.
Corrosion Resistance and Non-Magnetic Benefits
The nickel aluminium bronze construction eliminates spark generation and magnetic interference, critical for work near flammable vapours or sensitive instrumentation. Corrosion resistance extends service life in marine, chemical or outdoor settings where steel pliers would degrade. No insulation or tether points are fitted, so the tool is not rated for live electrical work or drop-prevention systems. The six-position joint maintains alignment across the full 2 1/8 in jaw range.

Questions about this item
How do I adjust the jaw to the correct groove without stripping the joint?
Open the handles, slide the tongue into one of the six grooves until it seats fully, then close the handles to lock the 2 1/8 in maximum opening.
Will the nickel aluminum bronze jaws need replacement or re-serrating over time?
The uncoated, corrosion-resistant bronze resists wear; serrations stay effective under normal use and the material is non-sparking and non-magnetic.
At what point does the cushion grip become the limiting factor during sustained heavy torque?
The standard cushion grip transmits force until hand fatigue or slip occurs before the 12 in lever arm or bronze jaws reach their structural limit.
