Spark-Resistant Pliers for Hazardous Areas

The Ampco Safety Tools P-39 is a 10 inch straight-jaw tongue and groove plier built from nickel aluminium bronze. This alloy makes the tool non-sparking, non-magnetic and corrosion resistant. It is designed for maintenance and assembly tasks in environments where flammable vapours, dust or sensitive magnetic equipment are present.

Fit for Ex-Zone Maintenance.

These pliers suit technicians in oil and gas, chemical plants or munitions facilities who must avoid ignition sources. The adjustable groove joint grips workpieces up to 1 1/2 inch wide. Buyers needing maximum clamping force for structural steel or high-torque fastening should choose hardened steel pliers instead, as the bronze alloy is softer than carbon steel.

Non-Sparking Nickel Aluminium Bronze Construction

The decisive specification is the material: high-strength nickel aluminium bronze that eliminates spark and magnetic signatures. This property allows safe use in classified hazardous locations where standard steel tools are prohibited. Verify that your site safety plan requires non-sparking hand tools before purchasing.

Questions about this item

Do I need a specific workpiece size for the 10 in plier to grip?

The straight jaw opens to 1 1/2 in. width, so any workpiece that fits within that span can be held.

Can I use the P-39 near magnetic equipment I already own?

Yes, the nickel aluminium bronze construction is non-magnetic and will not interfere with sensitive instruments.

How do I confirm the groove joint is adjusted correctly after setup?

The joint should lock with a single twist of the handle and the jaws must align evenly across the full 1 1/2 in. width without play.
