Schrader was founded in 1844 when August Schrader opened a brass machine shop in New York. He went on to invent the standard valve core still used in today’s tyre valves. The tubeless tyre valve, also known as a Snap-In valve, was invented and patented by Schrader in 1951. The Schrader-branded valve is manufactured with ethylene propylene (EPDM) rubber, which features superior resistance to heat, ozone, and automotive fluids. Schrader is widely known as the inventor of the industry-standard pneumatic tyre valve, the patented valve used on every motor vehicle in the world today. The Schrader tubeless tyre valve consists of overmolded rubber on a brass stem. Air-tightness is achieved by a core and a sealing cap mounted on the valve.
