Trumbull Manufacturing participated in the 2026 Tri Con Ocean City MD event at booth #224.

Trumbull Manufacturing began as outgrowth of Trumbull Industries which was founded in 1922 in Warren, Ohio (Trumbull County). Manufacturing operations started in 1981 to offer specialty products for the Municipal and Industrial markets. Product categories include waterworks tools, valve position indicators, polywrap, joint restraints products, meter pit lids and couplings, valve and curb box accessories, as well as valves and accessories for water/wastewater treatment plants. We specialize in unique and customized accessories for the valve market. We have pioneered cast stainless valve accessories such as stainless chainwheels, floorstands, wall brackets and stem guides. Other innovations include our valve position indicators and cast stainless mud valves that have been thoughtfully designed to meet the highest expectations of Engineers and Operators. In 1990, the Ludlow and Corey-Rensselaer hydrant product line was purchased. That acquisition expanded manufacturing capabilities and expertise in making repair parts for obsolete fire hydrants. Trumbull Manufacturing is a leader in providing thermoplastic and composite lids for water meter changeout programs, as well as composite manhole frames and covers. In 2017, Trumbull Manufacturing moved to a larger facility in Youngstown, Ohio, to accommodate growth and increase manufacturing capacity. Regional inventory is located in Rep warehouses in Orlando, Phoenix, Los Angeles, Dallas and Seattle. We stand behind our product with experienced Engineering, Quality Control and Field Service personnel. Our products are designed for long life, and are rigorously tested, in-house and at independent labs. Our inside sales staff is passionate about customer satisfaction. Trumbull Manufacturing sells to Waterworks distributors, valve representatives and manufacturers both nationally and internationally.
