Presta Schrader Valve adapter
Description
Another Presta-Schrader valve adapter. There are several models on Thingiverse, but nothing perfectly matches the different Presta valves (usually because the use of the body thread) So, I wanted to solve some problems: - the Presta internal thread of the adapter must correspond to the cap thread of the valve - suitable for several types of presta valves (see photos) - adapted with a compressor air inflator (Schrader valve) This model works perfectly. The fusion360 file is attached. 09/03/19 : New version (below the Presta thread : diameter increase to 7mm and height to 2.1 mm) to place an Oring (7,1 x 0.8 mm) to improve sealing when using an air inflator. You can adapt (fusion360 file) according to the Oring used.
