Adams Suction Cups - weight ratings and technical drawings



Weight ratings
Why is it that many other suction cup manufacturers do not publish weight ratings for their products?

Adams suction cups have weight ratings below* that are based on the applied mm diameter of suction cups with hooks when applied dry on clean, flat glass.

suction cups weight ratings-www.suctioncupsdirect.co.uk
22mm - 0.22kgs (0.5 lbs)
32mm - 0.45kgs (1 lbs)
47mm - 1.36kgs (3 lbs)
64mm - 3.2kgs (7 lbs)
85mm - up to 5.5kgs (12 lbs)
85mm - Pro Grade double suction hook - 9kgs (20 lbs)
85mm bird feeder suction hook:- see listing



*A screw-in fitting, push in fitting or slot head may lower the holding weight of an attached product due to:-
1. it's reliance on the thread made in the PVC
2. the grip of the push in attachment within the cup
3. the closing jaws of a self closing cup.

Suction cup diameters stated generally are applied dimensions. Technical drawings show suction cup diameters at rest.
If using Adams suction cups to incorporate into your own product, we recommend that adequate testing is carried out to ensure they will perform to your requirements.

Temperature ranges
Temperature and humidity variations may make a suction cup lose its grip.
Adams suction cups will hold between temperatures of MINUS 29C (-20F) and +49C (120F), but should first be applied above 5C (40F).


Application surfaces
Fix suction cups to dry, clean, flat, smooth, slick/shiny, non-porous, non-textured surfaces like glass, mirrors, glossy plastic, glazed ceramic tiles, car bodywork etc.

Surfaces like shower panels and tiles may have soap or cleaning product residue on the surface which needs to be removed with alcohol. Proprietary glass cleaners can leave a residue which affects adhesion. De-grease any application area and then clean with a mild detergent, rinse and dry.

The suction cup may need to be "burped" periodically by pressing down on it to remove any air that may have seeped in.


Adams Suction Cups with hooks Vs lever type suction hooks
Adams suction cups with hooks hold better than equivalent size suction hooks of the snap lock lever type or turn knob type found elsewhere.
