Plumbing, HVAC and hydronic equipment and parts distributor Hills Distribution has acquired Bender Plumbing Supply — a distributor headquartered in New Haven, CT.

Based in Meriden, CT,  Hills is owned by private equity firm Green Mountain Partners, which formed Hills in late 2024 as a plumbing and HVAC platform upon its acquisition of Plimpton Hills.

Founded in 1946, Bender Plumbing Supply is a fourth-generation, family-owned business. The company operates six locations and offers a comprehensive range of plumbing and HVAC products, complemented by showroom capabilities serving both trade professionals and homeowners.

In a March 30 news release, Hills Distribution announced that Max Bender will continue in his role as President, alongside the existing executive team, and will continue to lead the business.

“When we considered the next chapter for our business, it was critical to find a partner who shared our values and respected what has made Bender successful for nearly 80 years,” Max Bender said. “Hills Distribution and Grove Mountain Partners stood out for their integrity, long-term mindset and commitment to supporting our people, customers and brand. We are confident they are the right partner to help us continue building on our legacy.”

“We are delighted to partner with a company that reflects the same principles that define Hills Distribution — integrity, service and a long-term commitment to customers and associates,” added Stephen Fraser, Chairman of Hills Distribution and partner at Grove Mountain Partners. “Bender has built an outstanding business over decades, and we look forward to supporting their continued growth as part of the platform.”

Alongside Bender Plumbing Supply and Plimpton & Hills, Hills Distribution portfolio also includes fellow U.S. Northeast companies Coastal Supply Group and RJ Murray Company.
