About New England Union

The New England Union Company is a leading US manufacturer of cast and machined brass and bronze alloy piping/fluid handling products. Customers from major name-brand manufacturers to the US Navy rely on us to manufacture quality-assured fittings, valve bodies, flanges and other components to spec and on time.

Since our start in 1934 as a fittings manufacturer, four generations of the Petit family have applied the original innovation, ingenuity and devotion to craftsmanship set in motion by founder Theodore J. Petit.

Today’s NEU draws on those core principles using the latest, state-of-the-art technology, equipment and techniques to produce quality products that meet our customers’ toughest challenges – that add value to their products and that support their brand reputation.

A Brief History


Theodore J. Petit established the company in a rented Warwick, RI barn. Using salvaged equipment, the new company manufactured malleable iron pipe unions.


The company moved to a larger building.

Mid ‘50s:

NEU built a foundry that manufactured brass castings.


The company moved to its current West Warwick, RI location.


NEU converted to the induction melting process and committed to operations based on state-of-the-art technologies and techniques. That commitment continues to the current day.
