The Alligator Rubber Valve Puller, No. 231900, is designed to make the assembly of snap-in valves faster and more efficient. It features a pivoting joint that prevents the valve from being retracted at an angle, snap-in notches to ensure the correct angle, a long lever arm for optimal force application, and a soft plastic shaft that prevents damage to aluminum wheels. The tool also has a "click" mechanism in its head that allows rapid screwing onto the valve. The off-set and pivoting head ensures compatibility with most aftermarket wheels.
