During World War I and World War II, Leslie supplied military and merchant ships with steam control equipment.In 1968, after the company had expanded its product line to include industries and utilities, Leslie built a plant in Parsippany, New Jersey.Leslie moved to Tampa and was purchased in 1990 by Watts Industries, Inc. Leslie bought K&M Valve Company in 1995.Watts started Circor International in 1999 when it spun off valve and control businesses relating to oil and gas.On November 16, 2021, HornBlasters announced that they had acquired the Prestigious Air Whistles Division of Circor Leslie Controls, the oldest locomotive horn manufacturer in the United States.
