Custom 55mm double-sided silicone vacuum suction cup

A double-sided silicone vacuum suction cup provides two opposing suction-contact faces in one molded component. The 55 mm size designation should be considered with the full profile, including overall height and the shape of each face. Both receiving surfaces need to suit the cup for the arrangement to work as intended.

Check the available contact area on each side independently. A smooth first surface does not compensate for texture, curvature, or a seam on the second. The two surfaces also need to be positioned so the rubber is not held in a permanent twist or sideways bend after attachment.

Plan the fitting sequence and leave access for release. Pressing one face into place can disturb the other if the surrounding parts force the cup out of alignment. Evaluate the complete arrangement with the actual load, orientation, and expected movement rather than assigning capacity from the 55 mm designation alone. Keep both faces clean and inspect both lips for cuts or deformation. Recheck attachment after repositioning either side, and avoid locations where an unexpected detachment would cause injury or damage. A double-sided form requires two suitable contacts, not just one successful suction connection.
