These tools allow the user to service valve cores without losing the systems charge. Mastercool`s new unique design offers a locking device (patent pending) that holds the shaft in place while removing or installing the valve core. This remover/installer kit makes removal or insertion much easier, especially on the larger R- I 34a valve cores. Less down time saves money.
