Upgrade your vintage cooling system with this genuine Stant SP-9 Lev-R-Vent Radiator Cap. This is a vintage New Old Replacement Stock (NORS) part. Rated at 7 PSI, it is the correct pressure specification for many mid-1950s GM vehicles and early Corvettes. The Lev-R-Vent safety lever allows you to release pressure safely before removing the cap, preventing scalding.
This part is designed for the radiator filler neck on specific 1955-1961 Chevrolet Corvette (V8), 1955-1957 Chevrolet Passenger Cars, and various 1950s Hudson, Nash, and Pontiac models requiring a 7lb cap.
