Custom rubber silicone products suction cup with threaded screw

A suction cup with threaded screw can be customized for a rubber or silicone mounting component. The screw length, thread form and cup profile need to fit the surrounding assembly together. Space for the fastener should be considered alongside the clearance needed by the flexible cup when it contacts a surface.

Check whether the screw projects into another component or reaches the end of its mating hole before the intended seat is reached. At the opposite side, make sure the cup body can deform as designed without rubbing against a bracket. These checks prevent the mechanical connection from dictating an unsuitable contact position.

Select the finished material for the surface and operating environment. Evaluate the assembled cup in its actual orientation and under the intended use conditions. For maintenance, release the suction contact before removing the mounting connection, and avoid twisting the lip as a handle. Inspect both the attachment region and the contact edge before reuse. A replacement should preserve the required clearances as well as the visible diameter.

Material options

Custom silicone or rubber formulation; select the compound alongside the mating geometry.

Hardness selection

Silicone: 20–80 Shore A; solid rubber: 30–90 Shore A. Compare cup deformation in the mounted bracket, leaving the body room to flex without rubbing against the surrounding support.

Custom geometry

The screw length, thread form and cup profile need to fit the surrounding assembly together.

Fit evaluation

Evaluate the assembled cup in its actual orientation and under the intended use conditions.

Color & OEM

Custom colors; OEM markings outside the suction contact face.
