Ampco Safety P-39 Groove Joint Pliers | 10 in. OAL Non-Sparking, Non-Magnetic

The Ampco Safety Tools P-39 is a 10 in. non-sparking, non-magnetic groove joint pliers with soft grip handles, engineered for gripping pipe, fittings, and round stock in hazardous work environments.

Manufactured in the USA and Factory Mutual approved, it is beryllium-free and built for professionals who work around flammable or combustible vapors, liquids, dust, or residue where a standard steel tool could trigger a dangerous spark. Its non-magnetic properties make it safe for use near highly sensitive magnetic equipment, including MRI and clean room environments, and it conforms to ASTM F2503 and ASTM A342 standards.

Unlike conventional steel tools, the Ampco P-39 delivers outstanding durability even in the most corrosive conditions, including exposure to salt water, chemicals, and acids.

The P-39 groove joint pliers is the go-to choice for oil and gas, petrochemical, mining, military, and industrial maintenance applications where worker safety and tool reliability are non-negotiable.
