The Ascot Supply Professional Valve Puller is designed to protect wheels from scuffs, scratches, marks, and dings during installation and removal of snap-in valve stems. It is made of a durable plastic outside and is reinforced with an indestructible steel tube inside to provide extreme rigidity and increased strength. It has been tested to be virtually unbreakable and will not scratch or mar aluminum wheels, the company says. The professional valve puller is strong and reliable, while weighing less than 1 lb. The safety-orange color provides easy visibility for added convenience.
