Ampco K-21 Putty Knife Scraper 1.25 in Nickel Copper

Product Description

The AMPCO K-21 is a stiff-blade putty knife scraper built with a nickel copper blade and a wood handle. Nickel copper construction makes this tool appropriate for use in environments where spark resistance and corrosion resistance matter, such as refineries, chemical plants, and other hazardous-area job sites. The blade measures 1.25 inches wide and the overall length is 7.75 inches, giving the technician good leverage for scraping gaskets, removing putty, and general surface prep. The stiff blade flex makes it well suited to heavy scraping tasks where a flexible blade would deflect. This tool conforms to ASTM F2503, the standard specification for marking portable medical devices and other equipment where material composition must be confirmed.

The K-21 is used across industrial, mechanical, and facilities maintenance trades wherever a non-sparking or low-magnetic tool is required by site safety protocol. Common applications include HVAC equipment rooms, boiler rooms, compressor stations, and process facilities. It handles gasket scraping, adhesive removal, and surface cleaning on metal or masonry substrates. The compact 7.75-inch overall length keeps it manageable in tight mechanical spaces.

Key Features

• Nickel copper blade material for non-sparking, corrosion-resistant performance in hazardous environments
• Stiff blade flex for aggressive scraping and gasket removal
• 1.25-inch blade width for focused, controlled scraping
• 7.75-inch overall length with wood handle for grip and leverage
• Conforms to ASTM F2503 material marking standard

Compatibility

Designed as a general-purpose putty knife scraper for industrial and mechanical maintenance applications requiring non-sparking nickel copper tooling.

Installation Notes

This tool is intended for hand use by maintenance technicians, HVAC mechanics, plumbers, and facilities trades. No power source is required. Before scraping any surface on live equipment, shut down and de-energize the system per applicable lockout/tagout procedures. Follow site-specific hot-work and hazardous-area protocols when working in classified locations where non-sparking tools are mandated.
