Welded rather than sewn seams are the only way make 100% waterproof

PRESTA VALVES: The Presta valve (also called Sclaverand valve or French valve) is a valve commonly found in high pressure road style and many mountain bicycle inner tubes and tubeless systems. It comprises an outer valve stem and an inner valve body. A lock nut to secure the stem at the wheel rim and a valve cap may also be present.
The Schrader valve (also called American valve) is a brand of pneumatic tire valve used on virtually every motor vehicle in the world today. The Schrader company, for which it was named, was founded in 1844 by August Schrader. The original Schrader valve design was patented in the United States in 1893. The Schrader valve consists of a valve stem into which a valve core is threaded, and is used on virtually all automobile tires and most wider rimmed bicycle tires. The valve core is a poppet valve assisted by a spring.
