Elm City Tools specializes in designing and manufacturing hand tool solutions for several markets, including:


We have been manufacturing custom hand tools for plumbing applications since the 1970s, and offer a complete line of tools for PEX connection solutions including copper ring, stainless steel and pinch clamps.

We were on the board to establish ASTM specifications when PEX came into the industry, and our patented designs meet ASTM specifications and have set the standards for the industry.


In 1963, we worked with Packard Electric to design the first automotive application crimper. Since then, we have partnered with OEM manufacturers to developed complete lines of iconic designs for automotive weather-pack, metri-pack and micro-pack terminals.

We have also partnered with OEMs and tiers to develop tools to crimp a wide range of proven eMobility connections, and have developed pioneering tools for next-generation high and low voltage connections.

Our tools are distributed through OEM service networks.

Electrical, Electronic, Voice, Data, Video

We were instrumental in the development of crimping tools for terminals manufactured by OEMs such as AMP, Molex, Burndy, Amphenol, T&B, 3M and more.

To meet the needs of this exponentially dynamic growing market, we continue to innovate new solutions to meet the trade's professional demands. We can design and manufacture tools for various applications, from standard electrical terminals to cable preparation tools.
