Stant US Corporation was founded in 1898. Following World War I, the company began manufacturing auto parts, including the two-piece radiator cap. By the 1930s, it was producing hood ornaments, such as the flying quail ornament for the first Ford Model A and ornamental caps for various Lincoln, Packard, Pierce-Arrow and Cadillac models. Stant US Corporation has developed several products through the years, such as the LEV-R-VENT safety radiator pressure cap in 1962, the SWIV-EL radiator cap in 1985, and the PRE-VENT pressure-relieving fuel cap in 1987. It manufactures automotive fuel, radiator and oil filler caps, on-board refueling vapor recovery valves, and pressure, vacuum and fuel system testers. Tomkins acquired Stant Manufacturing in 1997.
