B&B introduces our new Posi-install valve stem seal tool. No more looking for those clear plastic valve stem covers. Our tool features a precision machined Seal Bullet which is placed over the valve stem. The seal is then inserted into the recess in the installer handle then easily centered over the "Bullet" for quick and easy seal installation. The "Bullet" is then stored inside the handle for re-use. Available in single sizes or as a kit.
