Our History

Tierney & Dalton Associates brings more than 30 years of industry experience to the New England PVF Market. T&D was established in June 1986, when we saw a need to provide competitive sources for both commodity items and some of the industry’s hard-to-find items. We became known as a one-stop shop for industrial piping products not only in New England but throughout the country.

Since our inception, we have expanded into valve automation, high purity piping products, waterjet metal cutting and polishing, fasteners, fabrication and much more. In today’s marketplace it is easy to get lost in the “mega store” mentality of PVF supply houses. Our clients find Tierney & Dalton refreshing because of our focus on complete customer satisfaction.
