Push-on valve cap with locking thread - seals the valve stem without screwing

摘要

The valve cap consists of metal or synthetic material, and has four parts, e.g. a valve cap sleeve, a locking part with locking thread, a locking spring, and a rubber seal. For positioning, the cap is held between two fingers. The locking part is pressed into the sleeve, and this causes the two thread halves to be moved away from each other. The locking spring is then positioned in round recesses of the sleeve and the locking part, causing the threaded halves to be pressed against the valve stem.
