Abstract
An air chuck for use with tire stems (or other air vessels) that use Schrader valves. In some embodiments, the air chuck has an outer threaded part that is rotated to urge a core with an O-ring to form a seal with the inner surface of the tire stem, preventing air leaks. The air chuck attaches via a single multi-turn rotary motion, which first creates the seal and then depresses the Schrader valve to allow air flow. This design offers improved air-pressure accuracy, simplicity, efficiency, ease of use, and reliability. Some embodiments further include a manually operable air valve and an air-pressure gauge operatively coupled to the air chuck.
