What type of valve is a Schrader valve?
Schrader valves use a spring-loaded check valve Unlike Presta valves, Schrader valves use a spring-loaded valve core, called a check valve. Presta valves aren't spring-loaded and instead use a valve core nut that holds the central pin in place.
What size are valve stem threads?
Presta valve stems are 6 mm in diameter, whereas Schrader valve stems for bicycle tires are 8 mm, allowing Prestas to be used on narrower, high-performance rims as on road racing bicycles.
Can I replace a tire valve stem?
Replacing your valve stem is an easy task to do, even if you aren't a mechanic. New valve stems cost about $10 dollars to repair if you do it yourself. If you bring it to the shop, it will cost about $30.
Are car TYRE valve caps universal?

I went through that a while ago. The external threaded part of a Schrader valve is 7.7 mm (.302") x 32 T.P.I.

That internal thread sounds awful close to 12-36. I bet a 12-36 tap would do the job.

Any time I need these threads, I take a discarded valve stem from the tire shop garbage, cut the rubber off, wire brush it clean and silver solder it in place. I even have one of these complete with core and installation tool/valve cap in the glove box in case some a**hole pulls a core on my vehicle again. Gerry :-)} London, Canada

What is the thread size of a Schrader valve?
What Is the Thread Size on a Schrader Valve? The external thread size of a Schrader valve is 0.305 inches outer diameter by 32 threads per inch (TPI), and it has a thread root diameter of 0.302 inches outer diameter.
What is the diameter of a Schrader valve?
The valve also has an internal thread of 0.209 inches outer diameter by 36 TPI. If no taps and dies of 0.305 inches are available, then 0.302 inch taps and dies are suitable replacements. The Schrader valve, also known as the American valve, is a pneumatic tire valve found on most motor vehicles around the world.
Who said tire valves are the ace of automotive standardization?
The late David Beecroft, former president of the Society of Automotive Engineers, said, "Tire valve development is deservedly the ace of automotive standardization.
What are valve cores made of?
The tiny valve cores are machined from brass rod and chrome plated. According to Mike Doster, a design engineer, seven different sizes of valve inserts for today’s tubeless tires and a couple dozen different lengths are made. "But, they’re all basically the same design, which hasn’t changed in over 100 years.".
How long has the Schrader valve been around?
The Schrader-valve has been an American standard for 102 consecutive years and a world standard for more than 76 years. George Schrader is credited with the pioneering effort and experimental work that resulted in patents issued for the current housing design with its removable and interchangeable core and cap.
Who invented pneumatic tires?
The Duryea brothers were the first car manufacturers in America to put pneumatic tires on their horse-less carriage; and if it hadn’t been for the invention of the tire valve by August Schrader and his son, George, there wouldn’t have been an air-tight seal to keep the tires from going flat over time.
