Gravity and friction are the two main forces that make it possible for suction cups to work. Gravity pulls the molecules in the air toward earth, creating atmospheric pressure of roughly 10.00 pounds per square inch at sea level. A good cup on a slick surface causes that pressure to be applied to the outside of the cup, pushing it down onto the surface. Friction keeps the cup from sliding.
Through years of R&D and testing, we’re developed an in-depth understanding of the science and other variables involved with maximizing suction cup performance. We developed the leadfar Suction Cup Performance Rating System™ to facilitate our R&D efforts. We are the world’s experts on suction cups. Our technical expertise is a big reason we are the most skilled suction cup producer.
