When the job is done this flexible tool can be looped and folded down to take up less space in your tool chest. The other side features a valve core installation tool so you can install and remove cores without having to go hunting for additional tools.The flexible cable is constructed of long lasting steel and ends in a cap that screws tightly onto valve stems and holds securely until the job is done. The handle and stem puller all feature a knurled finish texture to provide a non-slip grip in oily or wet conditions and each also spins freely of the main tool for ease of operation.
