Adams Worlds Best Suction Cups are Available Exclusively in the UK from Suction Cups Direct.

Adams USA are the World's suction cup experts and their technical expertise is a big reason why they are the most skilled suction cup producer and world leaders in suction cup technology.
Everyday suction cups have been manufactured by Adams in their own USA plants for over 25 years and their range is available from mini 22mm diameter to the giant 85mm diameter.


Adams patented light diffusing rings, stops a suction cup acting like a magnifying glass in sun light. Ordinary clear suctions cups concentrate light to a focal point which can damage interior surfaces behind the suction cup such as upholstery, curtains, car seats and dashboards.




Through years of R&D and testing, Adams have developed an in-depth understanding of the science and other variables involved with maximizing suction cup performance. They have developed the Adams Suction Cup Performance Rating System™ to facilitate their R&D efforts.




Understanding how suction cups work.
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 14.7 pounds per square inch at sea level, which acts in all directions.
When a suction cup is pushed onto a slick surface, the air underneath is expelled and a vacuum is created. As there is now no air pressure acting under the cup, only atmospheric pressure is being applied to the outside of the cup, so pushing it down onto the surface.
Friction keeps the cup from sliding.

Air can eventually leak back under the cup (so equalising the air pressure again), but a higher quality made suction cup dramatically slows downs this process and it performs better for longer.

Suction Cup finish and odour.
Suction cups work best when the inner surface is perfectly smooth and without the tiny irregularities caused by large vinyl molecules evaporating off the surface. Those evaporating molecules can be sensed by smell. The quality of a suction cup therefore, is directly proportionate to how much the suction cup's odour is sensed.

Suction cups that "smell" are literally losing their ability to hold molecules as they leave the inner surface. Adams suction cups are made of a proprietary blend of materials that keep them working better and longer than any other cup. A related issue is the appearance of the inner surface. Adams cups are shiny on the underside because any matt finish or insufficiently polished mold automatically means that air is going to leak in through the seal, causing cup failure. The laws of physics being what they are, any suction cup with less than a glossy finish on the underside, around the edge and extending into the cup, simply cannot stick as well.

By further adding a quick release tab, (as seen on most of Adams suction cups) this eliminates the damage to the cup edge caused by the "finger nail picking action" used to remove or re-position cheaper suction cups.

Adams Suction Cups versus Snap Lock Type
Adams cups of an equivalent size to "snap lock" type suction cups, hold better. Snap Locks preload the cup with the snap device, resulting in a greater pressure differential between the outside and underside which allows the air to migrate faster (the cup is continually trying to be pulled away from the applied surface).
